Abstract: Hydraulic inerter has excellent performance and high reliability, and can be well applied to automotive suspension systems. This article focuses on the nonlinear characteristics of hydraulic inerter, the simulation model is established by AMESim. Through simulation, it is found that at low frequencies, the frictional and damping forces of hydraulic inerter play a major role, while the inertial forces of inerter play a secondary role. But as the frequency increases, the effects of damping force and inertia force become more and more significant, while the influence of friction force becomes less and less significant. While the frequency is high, the influence of friction on the performance of hydraulic inerter can be ignored. Mechanical performance tests are conducted on a inerter test bench, and the correctness of the simulation model is verified through experiments, which is providing reference for further research on hydraulic inerter.

摘要： 液压惯容器性能优良，可靠性高，可较好地应用于汽车悬架系统。文章针对液压惯容 器的非线性特性进行研究，利用 AMESim 建立了液压惯容器的仿真模型。通过仿真得知在频 率较低时，液压惯容器的摩擦力和阻尼力起主要作用，而惯容器的惯性力起次要作用。但随 着频率不断增大，阻尼力和惯性力的作用越来越大，而摩擦力影响越来越小；当频率较大时， 摩擦对液压惯容器性能的影响可以忽略不计。在液压惯容器的台架试验台上进行了液力式惯 容器的力学性能试验，并通过试验验证仿真模型的正确性，为液压惯容器的进一步研究提供 参考。
