Problems solved by technology

[0004] Therefore, it is difficult to evaluate the structure and performance of high-speed wheel-rail systems based on theory alone. Most of them need to conduct a large number of experimental studies to obtain more reliable test data, which can then be used to guide production design; It takes a long time and has obvious disadvantages such as great impact on normal railway operation, and it is difficult to control the operating conditions

Abstract

The invention discloses a testing device for a wheel track system. The testing device comprises a bogie assembly; a vehicle mass simulation part mounted on the bogie assembly and used for simulating mass loading on the wheels; a fixed foundation hinged to the bogie assembly and the vehicle mass simulation component; a driving part used for driving the four wheels to rotate; four excitation assemblies respectively corresponding to the four wheels; and an excitation assembly used for loading transverse, longitudinal and vertical forces and loads to the corresponding wheels. The test device can simulate the motion states of the wheels under different working conditions indoors, is convenient to measure and high in measurement precision, has high reproducibility of test data, and can provide reliable test data for researching the wheel-rail relationship.

Description

technical field [0001] The invention relates to the technical field of rail vehicle systems, in particular to a test device for a wheel-rail system. Background technique [0002] The development of high-speed rail vehicles is rapid. Among them, the high-speed wheel-rail relationship is one of the key technologies of high-speed railways, which directly affects the traction power of locomotives, wheel-rail surface damage, train operation stability, and train braking. [0003] The operation of the train is realized by the traction and braking adhesive friction produced by the interaction between the wheel and the rail. The wheels roll on the track at high speed. The creep phenomenon of the form, at the same time, due to the traction and braking adhesion friction between the wheel and the rail, the interaction between the wheel and the rail becomes a more complex rolling form, and the interaction process is a complex tribological process . [0004] Therefore, it is difficult t...
