Electric power open loop hanging type transmission system reliability test stand

Abstract

The invention discloses an electric power open loop hanging type transmission system reliability test stand in order to overcome a problem that a motor train unit cannot conduct a motor train unit transmission system reliability test in the actual running process. The electric power open loop hanging type transmission system reliability test stand comprises a transmission system vertical vibration excitation device, a transmission system transverse vibration excitation device, a hanging support device, a gear box power open loop hanging vibration excitation assembly, a torque detection test device and an installation platform, and is characterized in that the transmission system vertical vibration excitation device is located at the right side of the installation platform; the hanging support device is installed on the transmission system vertical vibration excitation device, a simulated high-speed motor train transmission system assembly in the gear box power open loop hanging vibration excitation assembly is installed on a hanging basket in the hanging support device, two U-shaped bases are installed at the left side and the right side of the simulated high-speed motor train transmission system assembly respectively, a driving motor and the transmission system transverse vibration excitation device are located at the left side of the installation platform, and an electric eddy current dynamometer is installed on the ground; and the torque detection test device is installed on the installation platform at the front side and the rear side of the simulated high-speed motor train transmission system assembly.

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...
