Thank you again. I will try that. When i took in account only spring and damper i got in each case wheel lifting of the ground at some point. With gravity included, i guess this will change.

I am aware that mass should not lift off ground. That is why i am trying to determine when (at what speed v and/or at what period b) that happens. Because when that happens i think that this model is not appropriate anymore. Is it possible to determine that with values of contact force? If so...

Homework Statement In my homework I have to determine how do the speed (constant speed) (V) of damped mass and geometric characterictis of ground (b, h) influence on oscillation values of a model represented on a picture below. Model represents a vehicle driving on a sine wave ground. I...

Thank you Mentor for your reply. It looks like I will have to define d1 as well.

Hi, Can anyone help me formulate the equivalent spring and damper coefficients, for the problem represented on picture below. Can i just use the equations from the first post in this thread (only instead of using two springs in series, i would use three), or would that be wrong?
