摘　　要：在高速运行以及紧急制动时,动车组车下悬吊的重型设备会产生较大的动态载荷并发生一定频率的振动,对列车运行的安全性、平稳性、舒适性以及运行寿命都会有很大影响。为了减少这些因素的影响,对重型设备的分布、悬吊方式和悬吊结构进行了研究。In high speed operation and emergency braking,the heavy equipment suspended under multiple units may cause fairly great dynamic load and vibration of certain frequency,having great effect on the safety,stability,comfortability in operation of the train as well as the operation service life of the train.In order to reduce the effect of these factors,the distribution,suspension mode and the suspension structure of the heavy equipment are researched.

关 键 词：动车组 重型设备 悬挂 动态载荷
