建立1/4车辆液压主动悬架的数学模型;提出一种基于压力反馈的液压主动悬架系统,采用Modelica编程语言在Dymola软件平台上建立系统的仿真模型;通过仿真调试得到优化的控制参数,并通过样机实验将优化后的系统在强斜坡信号下的车身位移响应与被动悬架系统进行比较,车身的系统动态响应得到很大的改善.结果证明通过Modelica仿真语言和Dymola中的数值求解器可有效地解决系统多领域分析优化问题.

A model is built for active hydraulic suspension of the quarter—vehicle；Then asuspension systemis designed with pressure feedback contr01．The Modelica language is used in system programming and the Dy—mola is used for simulation．The desirable control parameters can be obtained by debugging．From the testingresponse figure of active hydraulic suspension and passive suspension，we can get that active systems greatlyimprove the dynamic performance．The result proves that we can successfully solve the problem of multi—do—main simulation and optimization by using the Modelica language and the numerical solver of Dymola．
