The Modeling and Simulation of Hydraulic Shock Absorber Based on Modelica

基于Modelica在液压管路系统建模中已获得了成功的应用。液压减震器是液压管路系统中的重要零部件,它的使用对减少液压系统中的振动、冲击和噪声等具有重要的作用。本文通过对两种常用的液压减震器——动压反馈装置和消音器进行工作原理分析,并利用Modelica建立仿真模型,最后给出实例验证了该方法的有效性。

Modelica-based modeling of the hydraulic piping system has been successfully applied .Hydraulic shock absorber is a hydraulic pipeline system ,an important component ,its use in the hydraulic system to reduce vibration ,shock and noise has an important role .Based on the two commonly used hydraulic shock absorbers-dynamic pressure feedback device working principle and the silencer analyzed and established using the Modelica simulation model ,and finally an example is given to verify the effectiveness of the method .
