*SetForce() - symmetric rotational

Sets the values for a symmetric rotational action-only or action-reaction force (torque) pair.

Syntax

*SetForce(force_name, LEFT|RIGHT, LIN, value_tx, 
                                            LIN, value_ty, 
                                            LIN,value_tz)

Arguments

force_name
The variable name of an existing rotational action-only or action-reaction force pair.
Data type: varname
LEFT RIGHT
If LEFT is specified, the properties are assigned to the left force, and the right force properties are made symmetric to the left force.
If RIGHT is specified, the properties are assigned to the right force, and the left force properties are made symmetric to the right force.
LIN
Keyword suggesting that a linear value is used to specify the force value. With symmetry, only LIN is valid.
Data type: keyword
value_tx, value_ty, value_tz
Numbers or MDL expressions that determine the values of the rotational force about the X, Y, and Z axis of the specified side of the force pair.
Data type: real

Example

*BodyPair(b_wheel, "Wheel body")
*PointPair(p_wc, "Wheel center")
*ActionOnlyForcePair(frc_wc, 
 "Applied force on wheel center", 
 ROT, 
 b_wheel, 
 p_wc)
*SetForce(frc_wc, LEFT, LIN, ds.real1.value * ds.real2.value, 
 LIN, 10.3, 
 LIN, ds.real3.value)

Comments

Solver expressions, curve data, or user subroutines cannot be used for symmetric force pairs.
