Hello,

 

A basic question : what is the difference between Bushes and Springs in MotionView ?

Is a Bush an element composed of 6 Springs/Dampers ? Or is it more complicated than that ?

 

Thanks for the answer !

    HI,

     

    Bushings are typically used to reduce vibration and noise, absorb shock, and accommodate misalignments.

     

    In MotonView, 

    A Spring Damper entity defines a spring damper acting between two Bodies. The element can be Coil Spring translational (applies a force) or Torsion Spring rotational (applies a torque). In both cases, the force is characterized by a stiffness coefficient, a damping coefficient, a free length and a preload

     

    A Bushing entity defines a force and torque acting between two Bodies. The force and torque consist of three major effects: a spring force, a damping force, and a preloadvector.
