A track bogie test bench

Abstract

The invention discloses a track bogie test bench. The track bogie test bench comprises two sets of simulation wheelset assemblies used for simulating the wheelset effect, a plurality of rocker supporting seats, a center seat, a plurality of actuators and a plurality of stress inductors; each set of simulation wheelset assemblies is detachably mounted on a rotating arm of a bogie, one ends of the multiple rocker supporting seats can be connected with a fixed foundation, and the other ends of the multiple rocker supporting seats are detachably arranged on the simulation wheelset assemblies; thecenter seat is detachably arranged in a traction pin seat of the bogie, the longitudinal displacement degree of freedom of the bogie relative to the center seat is constrained, and the torque and theswing degree of freedom of the bogie relative to the center seat are not constrained. By using the track bogie test bench, framework test work can be simultaneously completed, single test work of therotating arm can further be completed by arranging the simulation wheelset assemblies to simulate the wheelset effect, comprehensive test data are obtained by combining the framework test and the rotating arm single test, and thus the precision of the bogie test is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, and more specifically relates to a rail bogie test stand. Background technique [0002] With the development of high-speed freight trains, the integral frame bogie has gradually replaced the three-piece bogie, and the bogie test has become the key to whether the bogie meets the standard. Through the long-term load simulation test, the parameters of each stage of the bogie are tested, and the design defects are found out according to the parameters of each stage obtained from the test, and whether the physical bogie meets the specified requirements is judged, so as to obtain a bogie that meets the standard. [0003] At present, the frame bogie test mainly adopts the split method to carry out the test, the frame test work is completed on one test stand, and the single test work such as the jib is completed on another test stand. This kind of test method cannot measure comprehensive test da...

AI Technical Summary

Problems solved by technology

This kind of test method cannot measure comprehensive test data for important working conditions such as the pivoting arm and pivoting arm joints, and the accuracy of the conclusion is poor; each part of the load test is performed separately on the same test bench, and the bogie test takes a long time, which affects the product. R&D cycle: Two sets of load test equipment are required for separate load tests on two test benches, which require large investment costs, occupy a large site, and require multiple groups of operators to work at the same time
