Five-rod suspension is considered as a 5(S-S) platform-type in-parallel mechanism with flexible joints, the motion of which is controlled by a helical spring and shock-absorber. Quasi-static equilibrium position of the mechanism under given external load is found by using an iterative algorithm for elastokinematic analysis, including the displacement and force analysis procedures. Dynamic model of the suspension as a quarter car model is built in SIMULINK and uses nonlinear output of elastokinematic analysis including the effect of the shock absorber damping curve on the dynamic behaviour of the suspension.
