The subject of the paper are forced vibrations of the rear suspension of the biaxial vehicle fitted with the double spring spatial shell model and the viscous damper, under the force pulse input with the given transient response. The play between the master and auxiliary spring is a specific feature of the double spring design [1, 6]. Numerical tests were taken for three variants of the viscous attenuation. The attenuation coefficient values for typical dependent suspensions and their range of changes were assumed on the basis of publication [14]. The problem of modelling and analysing, including contact issues, was solved with the use of the MSC Software programme package with the special use of MSC Patran pre-processor [12]. The numerical analysis of the suspension model with the geometrical nonlinearities, viscous attenuation, and time-varying load was taken with the use of the finite element method (FEM). The selected results of the model tests in the form of the suspension relative displacements (speeds) and deformations (stresses) for the selected points of the master and auxiliary spring against time are presented in the paper. The complete model of the suspension system makes possible to examine the influence of various inputs on the interoperation and the phenomena associated with the dynamic response of such a complex system.
