Hi, I have a prblem in representing car model under impact with lumped parameter

  1. Aug 23, 2009 #1
    I had Kamal's model used for simulating frontal car impact. This model is represented by three masses and seven springs that represent structural elements of which the stiffness is obtained from static load deflection curves. I represented the model using simulink.

    My problem is what the necessary condition for loading/unloading/reloading for each spring (structural member) since each spring will be compressed according to the relative movement of the attached mass at its both end
    Kind regards
