Define the Mount Stiffness

Use Mount Stiffness when you want to approximate the structural deflection of the bodies that the bushing connects due to the load that the bushing carries. Mount stiffness is modeled as a set of linear springs and dampers in series with the bushing stiffness and damping, thus softening the connection between the bodies. Alternatively, you can use flexible bodies to model the bodies the bushing connects.

  1. Click Activate to add mount stiffness and damping for this bushing.
    MotionView adds a control state equation and other elements necessary to compute the deflection and rate-of-change of deflection of the bushing mounts due to the loads carried by the bushing.
  2. In the Stiffness Translational and Rotational fields, enter positive real values for the X, Y, and Z stiffness of the limits.
    Note: Translation dimensions are force and length-1. Rotational dimensions are force and length per radian.
  3. In the Damping Translational and Rotational fields, enter positive real values for the X, Y, and Z stiffness of the limits.
    Note: Translation dimensions are force, time and length-1. Rotational dimensions are force, length and time per radian.
