【摘要】 制动器是高速铁路列车及轨道车辆最重要的部件之一,其性能直接影响到行车安全。目前,我国高速铁路列车制动器主要依靠进口。为满足我国高速铁路列车制动系统研发和测试的需求,研制了可用于速度400 km/h及以下轨道车辆制动器性能测试的惯性试验台。文章介绍了该试验台的工作原理和结构,通过有限元分析校核了试验台惯性飞轮的强度,设计了全自动的飞轮切换机构,并模拟高速铁路列车实车制动器的安装方式设计了制动器安装吊架。设备交付用户实测表明,该新型试验台达到设计指标并满足相关测试标准要求。更多还原

【Abstract】 Brake is one of the most important parts for high-speed trains and rolling stock,and its performance directly affects operational safety. At present,the brakes for high-speed trains in China mainly rely on import. To satisfy the requirement of development and testing of high-speed train brake system in China,an inertia-dynamometer is developed which can be used to test the brake performance forthe rail vehicles with the speed of and under 400 km/h. In this paper,the working principles and structures of dynamometers are introduced. Through the finite element analysis,the strength of the inertial flywheel is checked and the fully automatic flywheel switching mechanism is designed,and the brake mounting hanger is designed to simulate the installation mode of the brake of the high-speed rail train. Equipment user shows after testing that this new dynamometer fulfills the requirements of design index and meets the relevant test standards.更多还原
