Abstract

The invention discloses a universal test bench for a high-speed train damper. The universal test bench for the high-speed train damper aims to solve the problems that an existing test bench of the damper is poor in performance, low in precision and high in cost. The test bench mainly comprises a mounting platform, a damper universal supporting assembling body, a vertical actuator assembling body, a bearing stand column, a transverse actuator assembling body, a damper variable angle mounting assembly and a longitudinal actuator assembling body; in the universal test bench for the high-speed train damper, the damper variable angle mounting assembly is connected with the vertical actuator assembling body, the transverse actuator assembling body and the longitudinal actuator assembling body; meanwhile, one end of the test damper is fixed, and the other end of the test damper is connected with the damper variable angle mounting assembly. The three actuators act under the control of a control system, the work state of the damper is represented truly, and meanwhile signals collected by a sensor are transferred to a detection system.

Description

technical field [0001] The invention relates to a parameter detection test device of a rail vehicle shock absorber. 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 the running speed of the EMU and the intensification of the vehicle axle load, the vibration between the EMU and the track is intensified, the running stability of the EMU is reduced, and the safety and running stability of the EMU have become increasingly prominent. The maintenance of the shock absorber is an important part of the maintenance of the EMU, and it is the key to ensure the safe and reliable operation of the EMU. [0003] The shock absorber is mainly used to suppress the shock when the spring rebounds after absorbing the shock and the impact from the ground or the track. It is a vulnerable part during the ope...
