摘　　要：高速动车组电空制动系统是由气动元件、电子元件和基础制动装置组成的复杂系统。基于现代流体力学的仿真分析软件AMESim建立制动系统中关键气动元件的仿真模型,通过试验数据对仿真模型进行验证和参数修正;将封装的气动元件模型与电子元件模型和基础制动装置进行系统集成,建立单车以及列车级电空制动系统仿真模型。基于列车级电空制动系统仿真模型,对高速动车组电空制动系统参数进行配置和分析,设计高速动车组电空制动系统。在最大常用制动和紧急制动2种工况下对基于仿真模型设计的高速动车组电空制动系统进行验证。结果表明:最大常用制动时减速度仿真值与减速度设计值相符;紧急制动时制动距离试验值为5 670m,仿真计算值为5 795m,相对误差为2.2%,仿真计算值与试验值吻合程度高。The electro-pneumatic braking system for high-speed EMU, characterized by high complexity, is composed of pneumatic components, electronic components and bogie brake devices. The simulation models for the key pneumatic components in braking system were built based on the simulation software of modern fluid dynamics AMESim. All the simulation models were validated and the parameters were modified according to experimental data. Single-car and train level electro-pneumatic braking system simu- lation models were established by integrating the packaged simulation models of pneumatic components, e- lectronic components and bogie brake devices. Based on the train level electro-pneumatic braking system simulation model, the electro-pneumatic braking system for high-speed EMU was designed by parameter configuration and analysis. The system for high-speed EMU designed based on simulation model was veri- fied under the working conditions of maximum service braking and emergency braking. Results show that the simulation values of deceleration are consistent with design values under the maximum service braking. The experimental value of braking distance is 5670 m while the simulation value is 5 795 m under emergen- cy braking and the relative error is 2.2~. The simulation values agree well with experimental values.
