Preload, Offset and Scale

The Preload/Offset/Scale tab displays the force characteristics of your bushing as you see in the following figure:

preload2

Select the Preload/Offset/Scale tab and the following appears:

preload

The Preload default value = 0; The Offset default value = 0; and the Scale default value = 1.0. The same holds true for both translational and rotational directions.

The following table describes the fields on this tab in more detail. Abbreviations are: [F] = force and [L] = length.

Option		Dimension	Description
Preload	Force X Y Z	[F]	Enter a real value. Positive preload (Pk) values act to attract the two bodies. See: Extended Definition for Preload, Offset and Scale.
Preload	Torque X Y Z	[F][L]	Enter a real value. Positive preload torque values act clockwise about the given axis (e.g. x, y or z) on body 1 and counter-clockwise on body 2.
Offsets	Disp X Y Z	[L]	Enter a real value. Displacement offsets (Qk) are subtracted from the actual displacement of body 1 with respect to body 2.
Offsets	Angle X Y Z	Radian	Enter a real value. Angle offsets are subtracted from the actual angular displacement.
Scales	Disp X Y Z	No Units	Enter a positive, real value. The displacement scale (Hk) scales both the input displacement and velocity, but not the displacement offset. The default value is one (1). See: Extended Definition of Preload, Offset and Scale.
	Angle X Y Z	No Units
	Force X Y Z	No Units	Enter a positive, real value. The force scale (Vk) scales the force function, but not the preload. The default value is one (1). See: Extended Definition of Preload, Offset and Scale.
	Torque X Y Z	No Units
