Description

technical field [0001] The invention belongs to the technical field of dynamic debugging and testing of railway vehicle bogies, in particular to a dynamic debugging test bench for railway vehicle bogies. Background technique [0002] With the development of high-speed railways and the deterioration of the service environment of various components in the operation of China's EMUs for more than ten years, the structural strength problems exposed to bogies, axles and car bodies have gradually increased. The environment is very different, so it is necessary to carry out the fatigue test of the bogie axle under various environmental conditions. [0003] With the increase of train running mileage, the bogie and rails have different degrees of wear and tear. The worn vehicle condition has more and more serious vibration impact on the bogie components, which greatly affects the life of the vehicle components. At the same time, with the opening of China's Xicheng high-speed railway,...
