Abstract

A rigidity detection system of four-column bogie of railway vehicles relates to railway vehicle performance detection equipment, which is designed for detecting the key kinetic parameters of bogie of railway vehicles under various motion states. The system comprises a mechanical system, a hydraulic system, a test system and a control system, wherein the mechanical system includes a gantry system (A) in frame structure composed of a crossbeam (1) and a vertical pillar (2), a five-degree-of-freedom force application system (F) composed of a simulated vehicle load pressure plate (5), a simulated vehicle load pressure column (4) and a simulated vehicle gravity center height adjusting mechanism (3), and a wheel pair positioning and clamping system (B) for clamping and positioning a rotation frame; the hydraulic system (E) includes a cylinder with vertical, longitudinal and transverse effects on the rotation frame; the test system includes a three-dimensional force detection system (G) and a rotation frame displacement detection system (C); and the control system is mainly composed of a hydraulic control system, an electric control system and a computer system.

Description

technical field [0001] The invention relates to rail vehicle performance testing equipment, in particular to a four-column rail vehicle bogie rigidity testing system. Background technique [0002] 1. The bogie testing facilities of foreign companies [0003] There are mainly two large-scale bogie production bases in Europe, one is Siemens' GRAZ company, and the other is ALSTOM's Coluso company. The European bogie production base and car body production are in different locations, so the car body is often not considered when testing the parameters of the bogie, but a platform is installed on the upper part of the bogie to simulate the car body. [0004] During the development of the new bogie, the European company calculated and optimized the suspension parameters of the bogie according to the line spectrum, but this is only a theoretical calculation. After the bogie is assembled, whether the primary, secondary, torsion and overall suspension parameters have reached The des...
