Embodiment Construction
[0050] The present invention is described in detail below in conjunction with accompanying drawing:
[0051] The purpose of the present invention is to provide an electric open-loop suspension type transmission system reliability test bench, which solves the problem that it is difficult to carry out the transmission system reliability test in the actual operation of the existing trains, so as to meet the needs of rail vehicle transmission systems in various operating conditions. The next reliability parameter detection needs. The transmission system vertical vibration device and transmission system lateral vibration device included in the test bench can accurately simulate the radial and axial loads on the transmission system in actual working conditions and the high-speed EMUs running on the actual line. Vibration conditions can truly reproduce the vibrations experienced by the transmission system of rail vehicles during operation, thus ensuring the correctness and authentici...

Description
technical field [0001] The invention relates to a test platform for detecting parameters of a rail vehicle transmission system, more precisely, the invention relates to a reliability test platform for an electric open-loop suspended transmission system. Background technique [0002] At present, my country's EMU technology is developing rapidly. The maximum speed of the EMUs in operation has reached 350km / h, and the maximum speed of the newly developed EMUs is close to 600km / h. With the increase of train speed and the increase of vehicle axle load, the vibration between the wheel and the track is intensified, the running stability of the vehicle is reduced, and the safety and ride comfort of the train are becoming more and more prominent. At the same time, with the on-line operation of a large number of high-speed EMUs, the maintenance work of EMUs at all levels is also carried out. Among them, the maintenance of the transmission system is an important part of the maintenance...
