Embodiment Construction

[0034] The present invention is described in detail below in conjunction with accompanying drawing:

[0035] The gearbox reliability test bench of the transmission system of high-speed EMUs described in the present invention can simulate the vibration condition of the train in actual operation. At the same time, the test bench itself also has a power drive system and a load system, which can simulate the very large output of the traction motor of the train. torque. In this way, the stress of the gearbox in the actual operating conditions of the train can be completely simulated. Over time, the gearbox will undergo fatigue damage, thereby realizing the reliability analysis of the gearbox of the high-speed EMU drive train. The technology for testing parameters of the high-speed EMU transmission system under vibration conditions is not yet mature in China. This high-speed EMU transmission gearbox reliability test bench has made a great contribution to the development of performan...

Abstract

The invention discloses a transmission system gearbox reliability test bed of a high-speed multiple unit. The transmission system gearbox reliability test bed of the high-speed multiple unit comprises an L-shaped bearer platform power flexible driving torque tester, a rectangular bearer platform power flexible driving torque detection tester, a trial gearbox assembly tester and a three-DOF (degree of freedom) vibration simulation test device, wherein the trial gearbox assembly tester and the three-DOF (degree of freedom) vibration simulation test device are mounted in parallel on the foundation, and a trial gearbox in the trial gearbox assembly tester is connected with a tested gearbox in the three-DOF (degree of freedom)vibration simulation test device through a synchronous universal joint coupling of a ball cage type. The L-shaped bearer platform power flexible driving torque tester is connected with the trial gearbox assembly tester trough a cross axial universal coupling, and the rectangular bearer platform power flexible driving torque detection tester is connected with the three-DOF (degree of freedom) vibration simulation test device through the cross axial universal coupling.

Description

technical field [0001] The invention relates to a test bed for detecting parameters of a transmission system of a rail vehicle, and more specifically, the invention relates to a reliability test bed for a gear box of a transmission system of a high-speed EMU. Background technique [0002] On the premise that our country implements the principle and policy of greatly increasing the speed of railways, the running speed of rail vehicles in our country has been greatly improved. This has also led to the rapid development of EMU technology. At present, the maximum speed of EMUs in operation has reached 350km / h, and the maximum speed of EMUs under development is close to 500km / h. However, with the increase of vehicle speed, the safety problems of EMUs have become increasingly prominent. Some key components, such as gearboxes, are prone to fatigue damage under high-speed driving and severe vibration environments. [0003] At present, there are many methods for testing the paramete...
