摘　　要：根据系统原理建立了可用于制动阀稳健设计及其制动压力响应特性分析的动态数学模型,试验验证了仿真模型的正确性。在分析系统制动特性主要影响因素的基础上,确定了制动阀的设计变量及不确定因素。对制动阀进行的基于制动压力损失最小的稳健设计结果表明,合理选择设计参数可使加工精度降低、制动性能的稳健性提高。研制的制动阀经工业性应用证明,系统性能满足国家标准要求。According to the principle of the system, a dynamic mathematical model for robust design of braking valve and for analyzing its responding characteristics was established. Experiments were conducted to verify the simulating model. On the basis of analyzing various factors affecting the main performances of the system, the design variables and the uncertainty factors of braking valve were conducted. The results of the experiment and simulation were used to develop the robust designs of braking valve and indicate that the reasonable design parameters can decrease the requirements of machining precision and improve the robust performance of braking performance. The quality of the brake system and its parts deigned have met the international standard through industrial utilization.
