摘要：
In order to reveal the nonlinearity of the new type of fluid inerter and its impact on vehicle suspension performance, a nonlinear dynamic model for fluid inerter is built involving the coupling of inner friction force, parasitic damping force and inertia force. The fluid inerter system is developed and its mechanical performance is tested with its results verifying the effectiveness of theoretical model. On the basis of study on two widely used ISD suspensions, a vibration model for a two-axle vehicle is constructed based on nonlinear fluid inerter to analyze its vibration isolation performance in a condition of random road input. The results show that the vibration isolation performances of two suspension systems are both subjected to the effects of nonlinearity of fluid inerter, mainly embodied in the deterioration of vibration isolation performance at low frequency segment. Compared with S2 suspension, the vibration isolation performance of S1 suspension is less affected by nonlinearity, exhibiting better performance superiority. © 2017, Society of Automotive Engineers of China.
