Analysis Requirements

To complete an analysis, you need to first define topography, setup, tower/tail hold positions and, analysis type and parameters.

1.	Topography

2.	Logging Setup

3.	Tower/Tailhold Positions

4.	Analysis Type and Parameters

Given Topography, Setup, Tower/Tailhold positions and Analysis Parameters, the Cable Analysis module will calculate the cable tensions and other results for several carriage positions between the landing and the tailhold. The values that are displayed are dependent on the screen layout and options selected. The carriage positions are automatically displayed in the Profile window. Other values such as cable tensions or midspan deflection can be displayed in sub-windows. Once the windows and options have been set up to display the results of a particular type of analysis they can be saved as a layout. A particular layout can be used to perform the same analysis on different topographies and produce comparable reports.


Topography

Topography is the ground profile under the cable. This is represented in Terrain by a feature (see Online Help for Terrain). A Terrain feature can be created by digitizing from a topographic map, or importing a traverse or map document from the Survey/Map module. You can also drape a feature over a terrain model by drawing with the mouse. Several features can exist in a Terrain file, the feature displayed the Profile/Cable Data Windows is defined in the Profile Window Options. Most commonly the Profile Window is set up to display the current feature; in this case, to select a profile for cable analysis, simply click on the feature in the Plan Window with the selection cursor (see Terrain Online Help for more information about selecting the current feature and displaying it in the profile window).


Analysis Parameters

The calculations performed can be selected from various options and parameters (e.g. load) which can be adjusted. The results of the analysis are displayed on the screen in the Profile window (graphic) and the Cable Analysis Data window (tabular). The format and contents of the display can be controlled by the user.

Several Analysis options and parameters can be chosen in a Calculation Options dialog box. For example, it is possible to calculate maximum load given clearance or fix the load and calculate minimum deflection. See the section describing the Cable Analysis - Calculation Parameters dialog box for more details. These options are saved with the screen/options layout file


Tower and Tailhold Positions

The location of the yarder and the tailhold and/or haulback block are stored with each feature. The tower position and tailhold/haulback position(s) are defined at the same time as a setup is chosen for the current profile. These positions and the name of the setup are then stored with the feature.


Creating a Logging Setup

A Logging Setup represents your yarder, cables and carriage. You choose a Logging Setup with the D-Line Assign Setup dialog box.

A Logging Setup is a combination of Equipment and Logging Configuration. You can create several pieces of equipment defined by tower height and cable strengths. For each of these pieces of equipment you can create one or more Logging Setups by defining different cable configurations and carriage types.

To create a Logging Setup.

1) From menu Cable Analysis - Equipment, create the equipment item you require.

2) From menu Cable Analysis - Setup - Add, create a new logging setup by combining the equipment with a Logging Configuration.


Equipment
The Equipment item contains the following information

- description eg. Thunderbird TY-90

- tower height

- default cable maximum working tensions (these can be modified for individual Logging Setups).

- maximum lengths of cable.


Logging Setups
The Logging Setup contains information defining the yarding machine, the configuration of the cables, working tensions and carriage parameters. To create a Logging Setup, you combine yarding Equipment with a Logging Configuration.

The Equipment can be defined in a dialog box while Logging Configurations are supplied by Softree; both are stored in a system file and are available at any time once defined. Similarly once a Logging Setup is defined it can be modified in a dialog box (independent of constituent Equipment and Logging Configuration) and can be saved for future use in the same system file.


Logging Configurations

The Logging Configuration contains the type of system (Shotgun, Slackline or Highlead etc.) and the carriage parameters (Dropline or Grapple or Butt Rigging...).

Logging Configurations are supplied by Softree. Below is a list of those configurations currently provided. If you cannot find a cable configuration which exactly matches your system, there may be one that is functionally the same.

Note that clamping does not have to be used during the analysis if your system does not have a clamping carriage.

Cable Analysis Overview

Finding a suitable yarding layout is generally an iterative process carried out by the forest engineer. During this process several different combinations of parameters are evaluated for feasibility. The engineer may change the elevation of the landing, move the tail hold or try using a setup with a lighter carriage. The interactive results allow you to test various configurations until a good solution is found or a bad one ruled out. For any workable solution, critical values such as maximum payload as a function position can be printed and used as guidelines during production.

The Cable Analysis software models a real cable harvesting system in many ways; however there are limitations to the model and the results should be used with intelligence.

The most obvious limitation of the model is that it exists only in two dimensions: Station and Elevation. The haulback block, for example, can only be placed in the plane defined by the tower and the tailhold.

The dynamics of yarding a log out from behind a stump are unique to each situation; for this reason all calculations are based on a quasi-static model. In a quasi-static model no part of the mechanical system is accelerating; thus the forces are balanced. From the engineer's point of view this means that a flying load moving slowly (or standing still) is modeled well. A log breaking out of a pile and then falling off a cliff is not modeled well because the friction and accelerations create forces that are not taken into account. Breakout Force can be modeled by adding an estimated value to the load but note that the direction of the effective load will not reflect reality.

As of this printing, a partially suspended load is not modeled. All loads due to logs are considered to act straight down from the carriage as if the load were flying. In fact the ground profile is only used to find the carriage elevation given ground clearance. If the software is asked to find the carriage position for a given midspan deflection it may show it as being under ground; the tensions will be reported as if the load were flying.

The carriage is modeled as a point. For example the mainline is considered to join the carriage at the same point the carriage is suspended from the skyline. This assumption will cause very little difference from reality.

The equations representing the model are precise except that the load due to the cable weight is assumed to be evenly distributed in the Station dimension. For a tight cable this is exactly true; if the cable sags slightly its tension is much more than its weight (most working cables) but the approximation is good; if the cable has a large sag so that both ends slope steeply down it is a bad approximation. If the approximation is poor the cable tension is small and it does not greatly affect the whole system.

Many results are calculated using iterative methods. The accuracy of these results (if one assumes that the model is perfect) will be somewhere around 99.9%. For example if you set the clearance and calculate the maximum load you will find that the limiting skyline cable tension will be just under it's working tension (perhaps 49985lb instead of 50000lb). The software has terminated its search for the correct load when the skyline load was close enough to maximum. The tensions and deflections calculated for a given load are accurate to floating precision (6 significant figures).

NOTE: The results from the computer calculated Cable Analysis should be interpreted with knowledge of the limitations of the model.


Types of Analysis

There are 4 types of analysis that can be performed on a given setup:

1.	Maximum Flying Load Given Clearance Option

2.	Minimum Deflection Given Load Option

3.	Deflection for Fixed Skyline Given Load Option

4.	Simple Third Point Deflection

Analysis parameters
The behavior of the three calculations can be modified by changing the Carriage Clamping, Haulback Tension and Calculation Interval parameters.


Maximum Flying Load Given Clearance

You define the carriage clearance from ground (which defines the deflection at each calculation point) and the computer calculates the maximum load that can be lifted each point. The load is limited by the working tensions in the cables.

This analysis shows the largest payload that can be lifted to a given height above ground. Although a large load may be lifted near the tail hold, it may not be possible to transport it back to the landing.

Note that no load can be lifted above the tight skyline position (chord) so some points may be impossible to calculate and will be left out of the results.


Minimum Deflection Given Load

You define the load and the computer finds the minimum deflection possible to lift the load without exceeding the working tensions of the cables.

This analysis is used to simulate the transport of the load to the landing when the skyline or haulback is dynamically adjusted. The carriage location shows the maximum possible clearance.


Deflection for Fixed Skyline Given Load

You specify the midspan deflection and load, the computer calculates the cable tensions and actual deflection for all the calculation points. Cables are allowed to exceed their working tensions.

This analysis is used to simulate the transport of the load to the landing when the skyline is fixed. The carriage location information shown in the Profile window is similar to the results of a chain and board analysis.


Simple Third Point Deflection

You specify the midspan deflection, the computer calculates the deflection at the 2 calculation points (third points).


Units

Cable analysis deals with quantities such as tension, weight, length and deflection. The common units used for these quantities are not standard and are usually mixed up (i.e. pounds for load, meters for distance). The Cable Analysis software is flexible with units; it is possible to define the units used for different quantities independently.

The units of Station and Elevation in the profile window are project units , defined in the ROADENG.INI file (usually meters or feet). These units are consistent with the Survey/Map and Location modules. Project units are also used for Skyline Length reports.

There are two force quantities that can be displayed with different units: tension and payload. Several dialog boxes allow you to change the default units for tension or payload (i.e. the Cable Analysis - Setup - Edit dialog box or the Cable Analysis - Calculation Parameters dialog box). For example, if you choose "lbs" while editing the cable working tensions the Tensions sub-window will then show "lbs" as will any tensions shown in the Cable Analysis Data window.


Output

1.	Cable Profile Window

2.	D-line Data Window


Cable Profile Window

The following sub-windows are available and can be selected for display using the Profile Window Options dialog.

Profile sub-window displays the ground line, chord between head spar and tail hold and the path of the carriage. It is always the top or main sub-window.

Tensions sub-window displays the skyline, mainline and haulback tensions. If you turn on Clamped Carriage in the calculation parameters then the carriage is clamped to the skyline and therefore the skyline tension is different before the carriage (Skyline HS - the head spar half) and after the carriage (Skyline TS - the tail spar half).

The units displayed in this sub-window may be changed by changing the units for line tensions in the Logging Setup Options dialog box.

Tensions Legend sub-window defines the line types and colors used for the graphics in the Tensions sub-window.

Skyline Length sub-window displays the length of the skyline from head spar to tail hold. (This may be the sum of the lengths of the mainline and haulback for a Highlead system or part of the length of the haulback for a running skyline.) The length can be displayed in project units or normalized (as a % of chord length, always greater than 100) for better comparison between different setups by Normalized in the sub-windows options.

Note that the Skyline Length is directly related to the Equivalent Midspan Deflection which may be more easily interpreted.

Load sub-window displays the payload at each calculated point. To change the units of this display, change Load units in the Calculation Parameters dialog box .

%Deflection sub-window allows you to display the deflection at each calculated point (vertical deviation from chord divided by the horizontal distance from head spar to tail hold as a %). You can elect to have the deflection calculated as an Equivalent Midspan Deflection by enabling Center Span in the % deflection sub-window options. This value is the deflection you would see if you moved a large load to midspan without changing skyline (or equivalent) length.

Note that the Equivalent Midspan Deflection is a measure of Skyline Length (independent of span).

Errors sub-window displays a red bar in areas where problems were encountered. A mouse click on the bar pops up one or more messages describing the problem(s). If the red bar fills the sub-window vertically then the calculations could not be calculated and no data for that region will be displayed in any of the reporting windows.

Note that sometimes calculation errors occur near the tail or head spar that may be safely ignored (it is not always possible to move a load very close to the tower or tail spar but still near the ground). To avoid these spurious errors adjust the calculation range in the Calculation Parameters dialog box (see Cable Analysis - Calculation Parameters).

Calculation Info sub-window displays information relevant to the current method of calculation.  For example "Minimum deflection given load, clamped load = 15000lbs."

Setup Description sub-window displays information relevant to the current setup. For example "slackline, sp carriage, SL, ML, HB, dropline, Sp Car, Car Weight = 10000Kg."


D-line Data Window

The D-line Data window displays tabular results of calculations.

The Cable Analysis Data window always displays the station at which the calculation is performed. It is measured as a accumulated horizontal distance (in project units) from the start of the feature. Underneath the station parameter you can choose using the D-line Data Options Dialog any of the following values:

Load is the calculated payload at each point. It does not include the carriage weight. The units in which the load is reported can be changed in the D-line Calculation Options dialog box.

Skyline Length is the actual length of skyline (measured in project units) from head spar to tail spar determined at each calculation point. (This may be the sum of the lengths of the mainline and haulback for a Highlead system or part of the length of the haulback for a running skyline.)

Note that the Skyline Length is directly related to the Equivalent Midspan Deflection which may be more easily interpreted.

%Deflection is the equivalent mid span deflection calculated at each point. This value is the deflection you would see if you moved a large load to midspan without changing skyline (or equivalent) length.

Note that the equivalent mid span deflection is a measure of skyline length (independent of span).

SkylineHS T is the tension in the skyline measured between the carriage and the head spar.  The tension between the carriage and the headspar will be different than the tension between the carriage and the tail spar when the carriage is clamped. The units reported can be changed by changing the Max. Working Tension units in the Logging Setup Options dialog box.

Skyline TS T is the tension in the skyline measured between the carriage and the tail spar. The tension between the carriage and the headspar will be different than the tension between the carriage and the tail spar when the carriage is clamped.  The units reported can be changed by changing the Max. Working Tension units in the Logging Setup Options dialog box.

Mainline T is the tension in the mainline. The units reported can be changed by changing the  Max. Working Tension units in the Logging Setup Options dialog box.

HaulBack T is the tension in the haulback. The units reported can be changed by changing the  Logging Setup Options dialog box.

Car Clear is the distance measured in project units between the ground and the point at which the carriage is suspended from the cable.

Car Elev is the elevation measured in project units of the point at which the carriage is suspended from the cable.
