Abstract：The geometric nonlinear dimensionless dynamical equations of suspension spring system were developed under action of a rectangular pulse, and the numerical results of the shock characteristics were studied using Runge-Kutta method. A new concept of three-dimensional shock response spectra was obtained, the ratio of the maximum shock response acceleration of the system to the peak pulse acceleration, the pulse duration and the angle of the suspension spring of the system were three basic parameters of the three-dimension shock response spectra. Based on the numerical results, the effects of the angle of the suspension spring and damping ratio of the system on the shock spectra were discussed. It was shown that the effects of the angle of the suspension spring and the damping ratio of the system are particularly noticeable, the damping can obviously decrease the maximum shock response acceleration of the system. The proposed method provided reference for design of shock absorber with suspension spring system.
