Abstract

The invention discloses a high-speed train axle box bearing test bench based on vibration rolling, which is characterized by comprising an electromagnetic vibration table (1), an extended table (2), a vertical force loading unit, a tested part, a spindle (12), a universal coupling (15) and a motor (16). The test bench can be used for axle box bearing test for a high-speed train at up to 350km/h.

Description

technical field [0001] The invention relates to a high-speed train axle box bearing test bench based on rolling vibration. Background technique [0002] Axlebox bearings are key components of the running part of high-speed trains. Their operating conditions, dynamic performance and service life have a vital impact on the safe, stable and efficient operation of trains. From the current actual operation of high-speed trains, it can be seen that various failures of axle box bearings have occurred frequently, and they have failed prematurely before reaching the rated life. [0003] Due to the particularity of the operating environment of high-speed trains, the axle box bearings are in service under very harsh and complex working conditions: (1) The operating interval of intercity trains (such as Chengdu-Chongqing, Yangtze River Delta) is short, and the vehicle starts, accelerates, decelerates, And braking is frequent, which means that the dynamic load range of the axlebox beari...
