The following figure shows the effect of preload and offset on a bushing:
The bushing force for the Kth direction (x, y, z, ax, ay, az) is defined by a function:
Where:
The displacement offset Qk and the displacement scale Hk modify the displacement and velocity to compute new inputs to function G as follows:
|
is the scaled, offset displacement. |
|
is the scaled velocity. |
So force is then computed using the modified inputs |
|
and |
|
: |
Finally, the force/torque preload Pk and force/torque scale Vk modify the output so the force computation is:
