*ActionReactionForce() - line of action

Creates an action-reaction translational force acting along the line joining the points of action and reaction.

Syntax

*ActionReactionForce (force_name, "force_label", LOA, body_1, body_2, point_1, point_2)

Arguments

force_name: The variable name of the action-reaction force of type LOA.; Data type: varname
force_label: The descriptive label of the action-reaction force of type LOA.; Data type: label
LOA: This argument indicates the action-reaction translational force acts along the line joining point_1 and point_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 on body_1 at which the action force is applied.; Data type: Point
point_2: The point on body_2 at which the reaction force is applied.; Data type: Point

Example

*Point(p_jnc_frame, "Jounce bumper pt on frame")
*Point(p_jnc_axle, "Jounce bumper pt on axle")
*Body(b_axle, "Axle", p_axle_cg)
*Body(b_frame, "Frame", p_frame_cg)
*ActionReactionForce(frc_bmp, "Jounce bumper force", LOA, b_axle, b_frame, p_jnc_axle, 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.
f	real	A number, MDL expression, or solver expression that determines the value of the 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 LOA is used to apply action-reaction forces on two bodies along the line joining the two points at which the action and reaction forces are applied.
