*ActionReactionForce() - single component rotation

Creates a single component action-reaction rotational force (torque) acting about the given axis.

Syntax

*ActionReactionForce (force_name, "force_label", SC_ROT, body_1, body_2, point_1, {POINT VECTOR}, {point_2 vector_2})

Arguments

force_name: The variable name of the action-reaction force of type SC_ROT.; Data type: varname
force_label: The descriptive label of the action-reaction force of type SC_ROT.; Data type: label
SC_ROT: This argument indicates that the action-reaction rotational force acts about either the line joining point_1 and point_2 or about vector_2 .
body_1: The body to which the active force is applied.; Data type: Body
body_2: The body to which the reactive force is applied.; Data type: Body
point_1: The point used to define the rotational axis.; Data type: Point
POINT | VECTOR: A keyword that indicates the alignment method.
point_2 | vector_2: An entity variable referring to a Point or Vector which is based on the above keyword.; Data type: Point or Vector

Example

*Point(p_jnc_frame, "Jounce bumper pt on frame")
*Point(p_jnc_axle, "Jounce bumper pt on axel")
*Body(b_axle, "Axle", p_axle_cg)
*Body(b_frame, "Frame", p_frame_cg)
 
*ActionReactionForce(frc_bmp, "Jounce bumper force", SC_ROT, b_axle, b_frame, p_jnc_axle, POINT,  p_jnc_frame)

Context

*BeginMdl()

*DefineAnalysis()

*DefineSystem()

Properties

Property	Returns Data Type	Description
b1	Body	Body to which the force is applied.
b2	Body	Body to which the reactive force is applied.
t	real	A number, MDL expression, or solver expression that determines the value of the rotational force.
i	Marker	Marker attached to b1.
j	Marker	Marker attached to b2.
label	string	The descriptive label of the action-reaction force.
state	boolean	Control state (TRUE or FALSE).
varname	string	The variable name of the action-reaction force.
id	long integer	The solver ID of the action-reaction force.

Comments

*ActionReactionForce() of type SC_ROT is used to apply action-reaction forces on two bodies about the line joining two points or about a given vector.
