摘　　要：以某重型卡车的气制动阀为研究对象,介绍气制动阀的结构及工作原理,建立其动态数学模型。针对气制动阀工作过程中存在响应迟滞、动态特性分析较为复杂等问题,采用AMEsim软件搭建相应的仿真模型;然后根据仿真结果分析气制动阀的动态响应特性,并找出影响气制动阀动态响应特性的关键因素。结果表明:气制动阀仿真模型准确可靠,性能良好,能够满足仿真需求,平衡弹簧刚度、上腔活塞直径、上腔阀杆直径等是影响气制动阀动态响应特性的关键因素,为后续气制动阀的优化设计提供有力的参考。Taking the air brake valve of a heavy truck as the research object, the structure and working principle of the air brake valve are introduced, and its dynamic mathematical model is established.Aiming at the problems of response delay and dynamic characteristic analysis of the air brake valve in the working process, AMEsim software is used to build a corresponding simulation model, then the dynamic response characteristics of the air brake valve are analyzed according to the simulation results, and the key factors that affect the dynamic response characteristics of the air brake valve are found out. The results show that the air brake valve simulation model is accurate and reliable and has good performance,which can meet the simulation requirements. The balance spring stiffness, upper cavity piston diameter,and upper cavity valve stem diameter are the key factors affecting the dynamic response characteristics of the air brake valve, which provides a powerful reference for its subsequent optimization design.
