Force/torque properties can be defined along/about three axes of the local reference
marker using the Fx/Tx, Fy/Ty, and Fz/Tz fields in the Properties tab. In case of a Line of
Action translational force, the line defines the direction of application and the property
can be defined in a single field provided. The same is true for a Single Component
Rotational torque.
-
Click either the Trans Properties tab or the
Rot properties tab.
The Trans Properties tab is displayed when the selection in the Properties
drop-down menu in the Connectivity tab is set to either Translational,
TransRotational, or Line of Action Translational.
-
Specify how to define the translational/rotational properties in each direction
using the drop down menus.
If Linear is chosen, enter a constant value of
displacement, velocity, or acceleration.
If Curve is chosen:
-
Select AKIMA, CUBIC,
LINEAR , or QUINTIC under
Interpolation as the method of interpolation of between two data points
in the curve.
-
Enter a value under Independent variable.
-
Resolve the curve by double-clicking the Curve
collector and selecting a curve from the Select a
Curve dialog.
Note: To use a curve, you first need to define a curve (using the Curves
panel) which represents the behavior of the force.
If Sline3D is chosen:
-
Select AKIMA, CUBIC,
LINEAR , or QUINTIC under as the
method of interpolation of values between 2 data points in XY
plane.
-
Resolve the 3D spline by double-clicking on the
Spline3D collector and selecting a Spline3D
entity from the Select a Spline3D dialog.
Note: To use a Spline3D entity, you first need to define a spline using
the Spline3D panel.
-
Specify an expression for Independent variable X and Independent
variable Z.
If Expressions is chosen, enter a solver expression to
define displacement, velocity, or acceleration.
-
Repeat the same step for the second properties tab if needed.
