Abstract
The zero-stiffness structure has excellent vibration attenuation performance. In this paper, a new type of zero-stiffness vibration isolator is designed, and the vibration isolation effect is simulated and analyzed. Furthermore, the zero-stiffness isolator is applied to the McPherson suspension, and the improved McPherson suspension model is obtained. Under the excitation of the bump road and C-level Road, the performance of the improved suspension is simulated, and the responses of the vehicle body vertical acceleration and suspension deflection are analyzed, and compared with that of the original suspension. The results show that, under two cases, the vertical acceleration of the improved suspension is reduced by 92.5% and 65.4% compared with the original suspension respectively, and the stability speed is also greatly improved.
