摘要
在对串联式液压制动阀结构与性能分析的基础上,建立了全动力液压制动系统动态数学模型,并就制动阀结构参数对系统动态性能的影响进行了仿真分析.通过系统动态响应特性台架实验,验证了仿真模型,得出了各种制动工况对系统响应特性的影响规律.经工业性应用,设计研制的工程车辆全动力制动系统性能满足ISO3450标准要求.
Dynamic characteristics of a full power hydraulic brake system are directly related to the safe travel performances of vehicles. On the basis of the structure and performance analysis of a serial hydraulic brake valve, a simulating model of responding characteristics in a full power hydraulic brake system was established, and the simulation analysis of various structure parameters of the braking valve affecting the dynamic characteristics of the system was conducted. Experiments were conducted to verify the simulating model, to learn the affecting laws of many different brake means of vehicles on response characteristics of the system. The quality of the deigned brake system and its parts for construction vehicles has, through industrial utilization, met the requirement of ISO 3450.
