Modelling Half Car Suspension Help

  1. Nov 18, 2008 #1

    I was reading through the following report that I found on the web, in it is an equation I am very unclear on. Its equation 1, page 5.

    I think that equation relates to ma = F(left) + F(right) - mg as it describes body height.

    So I was wondering why on the LHS of the equation it has

    a + 2/m (Cl + Cr)v + 2/m (kl + kr)z?

    I replaced the z's wit their equivalents i.e z = x
    z dot = v
    z dot dot = a

    Could anyone take the time to look at the diagram (in the tables page shown at the end) and explain that part to me?
