*ActionReactionForce()

Creates an action-reaction force.

Syntax

*ActionReactionForce (force_nam e, "force_label", { TRANS ROT TRANS_ROT }, body_1, body_2, point, Optional: ref_marker)

Arguments

force_name: The variable name of the action-reaction force.; Data type: varname
force_label: The descriptive label of the action-reaction force.; Data type: label
TRANS | ROT | TRANS_ROT: This argument indicates whether the action-reaction force has translational, rotational, or both translation and rotational components.
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: The point at which the force is applied.; Data type: Point
ref_marker: An optional argument for the reference marker in which the components of the force are specified.; Data type: Marker

Example

*Point(p_jnc_bmp, "Jounce bumper pt")
*Body(b_axle, "Axle", p_axle_cg)
*Body(b_frame, "Frame", p_frame_cg)
*Marker(mrk_ref, "Force reference", b_axle, p_wc)
 
*ActionReactionForce(frc_bmp, "Jounce bumper force", TRANS, b_axle, b_frame, p_jnc_bmp, mrk_ref)

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.
b3	Body	Body to which the reference marker is attached.
fx fy fz	real or string	A number, MDL expression, or solver expression that determines the value of the translational X, Y, and Z components of the force.
i	Marker	Marker attached to b1.
j	Marker	Marker attached to b2.
jfloat	Marker	Floating marker attached to b2.
label	string	The descriptive label of the action-reaction force.
id	long integer	The solver ID of the action-reaction force.
rm	Marker	The reference marker in which the components of the force are specified.
state	boolean	Control state (TRUE or FALSE).
tx, ty, tz	real or string	A number, MDL expression, or solver expression that determines the value of the rotational force about the X, Y, and Z axis.
varname	string	The variable name of the action-reaction force.

Comments

*ActionReactionForce() is used to apply action-reaction forces to points on bodies.

If the optional argument for ref_marker is not specified, a global inertial frame is used as the reference marker for specifying force components.
