Abstract

The invention discloses a fault simulation test system for a bullet train wheel set assembly. The fault simulation test system comprises a test platform and a motor driving assembly. Two sets of simulation devices with the same structure are arranged on the test platform side by side, and the two sets of motor wheel pair assemblies are fixedly connected to the two sets of simulation devices respectively and are connected through a coupler. The simulation device is used for simulating one or a combination of more of a horizontal working condition, an ultrahigh working condition and a ramp working condition so as to complete a simulation test of the bullet train wheel pair assembly; the motor driving assembly is used for providing driving force needed by rotation of a traction motor of the bullet train wheel pair assembly. The system has the advantages of being compact in structure, convenient to install and adjust, high in applicability, capable of simulating a single working condition or multiple combined working conditions and the like, and well meets the simulation test requirements of different types of motor train unit motor wheel pairs for a transmission assembly.

Description

technical field [0001] The invention mainly relates to the technical field of rail vehicles, in particular to a fault simulation test system for a moving wheel pair assembly. 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 wheel sets, gearboxes, traction motors, etc., are prone to fatigue damage under high-speed driving and severe vibration environments. With the increase of the train speed and the aggravation of the vehicle axle load, the vibration between the vehicle a...
