摘　　要：针对在研究制动阀动特性时制动控制过程非线性严重以及数学公式难以推导的问题,以某公交客车气制动阀为研究对象,基于制动阀的物理结构和气动建模理论,利用AMEsim建立了包括内部元件结构参数的气制动阀仿真模型,分析了制动阀内部关键元件结构参数对阀动态响应特性的影响。搭建了实验平台对模型进行实验验证。结果表明:仿真结果与实验结果相吻合,且满足测试要求,验证了模型的准确性。该模型为制动阀的结构优化设计和整车制动性能分析提供给了依据。To solve the inadequate problem of domestic research in air brake valve, taking the brake valve of a bus as a re- search object, an air brake valve model was developed by AMEsim based on the physical structure of the air brake valve and pneu- matic modeling theory. The effects on the dynamic characteristics of brake valve by internal structural parameters of the key compo- nents were discussed. And a testing system was set up to verify the accuracy of the model. It shows that simulation results are in good agreement with experiment results, meeting the testing requirements. This model provided the data basis for structural optimi- zation of brake valve and performance analysis of brake system.
