Calculations in scripting

The runCalcMethod(methodID, compID); function is used to start calculations in scripting. As parameters, the function requires the ID of the calculation of the method and the ID of the component to be calculated.

System calculations are always performed for the component type "gear_unit". The ID of the calculation method is always "001_SYSTEM_CALCULATION". To add additional calculations to the system calculation, the corresponding calculation attributes must be set to true.

For individual component calculations the calculations are always performed for the respective component. There are different calculation methods available for each component type.

By right-clicking on a calculation, the associated ID can be copied to the clipboard and pasted into the script.

System calculations

Example: System calculation with activated load capacity calculation according to ISO 6336

1var gearUnitID = 1;
2setAttr("gta_switch_iso_6336_2006", gearUnitID, true, EDAT);
3runCalcMethod("001_SYSTEM_CALCULATION", gearUnitID);

1

Assigns the variable GearUnitID with the ID of the component "gear unit" (Tip: the ID of the gear unit is always 1).

2

Sets the attribute for the "load capacity according to ISO 6336 (2006)" calculation switch to true.

3

Runs the system calculation.

Example: calculate the bearing life for a single rolling bearing

1var bearingID = 10;
2runCalcMethod("800_ROLLING_BEARING_LIFETIME", bearingID);

1

Assigns the ID of the rolling bearing to the bearingID variable.

2

Performs the single component calculation with the "800_ROLLING_BEARING_LIFETIME" methodID.

Tip

You can also specify only the method number "800" instead of the complete method ID "800_ROLLING_BEARING_LIFETIME."
