The Resonance Property of Shock Absorber System With Tilted Spring Under Foundation Displacement Excitation

The nonlinear vibration equation is found for shock absorber system with tilted spring under foundation displacement excitation.Then the resonance property of shock absorber system with tilted spring is studied.And its amplitude-frequency response equation is derived by KBM method.The numerical example indicates that the resonant region for shock absorber system with tilted spring increased with the increase of the amplitude of foundation displacement excitation and the spring tilt angle.
