在主动悬架系统中作用力产生装置模型的建立及性能分析

摘要

With apply force produced by hydraulic system,active suspension system can improve comfort and safety of automobiles.Dynamic performance of hyd raulic system directly affects on controlling process of apply force. Through an a lysis on the work process of hydraulic cylinder,the mathematical model of hydrau lic cylinder state is developed and the computation and analysis on its dynamic performance are carried out to set up suitable controlling system of active susp ension.%主动悬架系统通过液压装置产生的作用力来改善汽车的 行驶平顺性和行驶安全性(通过性)，而液压系统的动态特性直接影响作用力的控制过程。通 过对液压缸工作进行分析，建立了液压缸工作状态的数学模型，并对它们的动态特性进行了 计算和分析，为主动悬架系统的实现及控制系统的正确建立提供了理论基础。
