The forced vibration of a dependent rear suspension model of the two-axle vehicle, equipped with a 3D model of a double spring and a viscous shock absorber is the subject of consideration. The clearance between the master and auxiliary springs is a specificity of the double suspension construction. Dynamic analysis of such a system has been performed by forcing with different forms of force pulses using the fixed base of force 10 kN. Three different time runs (two trapezoidal and one triangular model) are used as the force impulses. Modelling and analysis taking into consideration contact problems have been developed using the MSC.Software package with a special use of Patran pre-processor and Nastran solver. A finite element method (FEM) has been used in numerical analysis of the suspension model with geometric nonlinearities, viscous damping [9] and time-varying load. The boundary conditions of numerical models correspond to a spring support in the real vehicle suspension. The non-periodic damped vibrations and damped free vibrations of the simplified suspension system are investigated during numerical analysis. Selected results of the model tests have been presented in the form of the timings of the accelerations of the spring elements and of the forces in the suspension damper.
