Embodiment Construction

[0051] The present invention is described in detail below in conjunction with accompanying drawing:

[0052] The invention provides a reliability test bench for a two-body six-dimensional vibration drive train assembly of a high-speed EMU to meet the requirements for detecting reliability parameters of a rail vehicle drive train assembly under various operating conditions. The test bench adopts the structural design of a reasonable load simulation system, which avoids the danger and loss caused by the destructive test on the actual running vehicle. Two sets of three-degree-of-freedom vibration simulation test The external excitation is applied to the gear box assembly to simulate the vibration of the high-speed EMU in the actual track, which provides a good test basis for the reliability test of the high-speed EMU drive train and ensures the accuracy and correctness of the test. The tests done are all destructive tests, so that the cause of the failure of the traction motor be...

Abstract

The invention discloses a reliability test bench of a two-body six-dimensional vibration drive train assembly for a high-speed motor train unit, and solves the problem that a drive train is put into a static environment to respectively research a reducer or a drive motor in the prior art. The reliability test bench comprises a three-degree-of-freedom vibration table of a vibration shaft assembly and a three-degree-of-freedom vibration table of a traction motor assembly, wherein the three-degree-of-freedom vibration table of the vibration shaft assembly and the three-degree-of-freedom vibration table of the traction motor assembly are arranged on a foundation back to back in parallel; the three-degree-of-freedom vibration table of the traction motor assembly comprises a second three-degree-of-freedom vibrating simulation test device, a traction motor, a fixing clamp assembly body and a drive train gear box fixed bracket assembly body; the second three-degree-of-freedom vibrating simulation test device comprises a second vibrating T-shaped beam, a second transverse actuator, a third vertical actuator and a fourth vertical actuator; the traction motor, the fixing clamp assembly body and the drive train gear box fixed bracket assembly body are fixedly connected to the upper surface of the second vibrating T-shaped beam.

Description

technical field [0001] The invention relates to a test platform for detecting parameters of a rail vehicle drive train assembly, more specifically, the invention relates to a two-body six-dimensional vibration drive train assembly reliability test platform for high-speed EMUs. Background technique [0002] At present, my country's EMU technology is developing rapidly. The maximum speed of EMUs in operation has reached 350km / h, and the maximum speed of EMUs under development is close to 500km / h. With the increase of train speed and vehicle axle load, the vibration between the vehicle and the track is intensified, the running stability of the vehicle is reduced, and the problems of train safety and ride comfort are becoming more and more prominent. [0003] According to the analysis of train faults in actual operation, the drive train of high-speed trains is the weak link when trains run at high speed. Due to the large transmission torque, high gear speed and excessive vehicl...
