重型车辆制动系执行机构虚拟样机仿真研究

Run Simulation of a Heavy Duty Vehicle Brake Apply System

用机械系统动力学分析软件ADAMS对某重型车辆制动系建立虚拟样机模型 ,模拟制动系统在制动建压中的动态过程 ,结合已验证的数据对仿真结果进行分析 ,验证了实体模型的正确性。在此基础上 。

In this paper,a virtual prototype of a heavy duty vehicle brake apply system is created by making use of ADAMS.The dynamic process of the increasing pressure during braking is simulated with the model,then the simulation results are compared with the result,which is been validated.Their identity indicates that the model is correct.On the basis of these results,the paper does some research on dynamic characteristic of the system and braking contact force.
