Fault simulated test bed for train frame suspended driving system of high-speed motor train unit

The invention relates to a fault simulated test bed for a train frame suspended driving system of a high-speed motor train unit. The test bed is designed by referring to a driving device of a train ofa CRH3 type motor train unit and is composed of the driving device, a gear box transmission device, an inertia simulation device, a force measuring sensor device, a braking device, a T-shaped base rack and the like. On the basis of the train of the CRH3 type motor train unit, the test bed can simulate and monitor dynamic behaviors and fault modes of the driving system during power harmonic operation of a traction motor under a flexible floating gear coupling misalignment fault, a suspension device rigidity degradation fault, or a transmission gear engagement fault and a gearbox bearing fault.Thus, the test bed has significance in fault-mode operation of the train frame suspended driving system of the high-speed motor train unit. 本发明涉及一种高速动车组列车架悬式驱动系统故障模拟试验台，该试验台参照CRH3型动车组列车的驱动装置进行设计，由驱动装置、齿轮箱传动装置、惯量模拟装置、测力传感器装置、制
