Abstract：The nonlinear vibration equation was found for shock absorber system with tilted support spring under foundation displacement excitation，the question of nonlinear vibration was also studied．The approximately solution of nonlinear vibration for shock absorber system with tilted support spring was derived by L-P method，the affect was discussed and analyzed for amplitude and frequency of foundation displacement excitation，oblique angle of tilted support spring and so on to the nonlinear vibration of shock absorber system with tilted support spring．At last the conclusions was got that the shock absorber effect of shock absorber system with tilted support spring is better than shock absorber system with vertical installed spring，the proposed method provides academic foundation for shock absorber design with tilted support spring．
