Fatigue and vibration experiment table and system

Abstract

The invention provides a fatigue and vibration experiment table and a fatigue and vibration experiment system. The fatigue and vibration experiment table comprises two fatigue and vibration experiment modules, a longitudinal platform, a longitudinal loading framework and a longitudinal loading device, wherein each fatigue and vibration experiment module comprises two vibration units, a fatigue unit and a bearing platform; the two vibration units are arranged on the bearing platform in a sliding way; the fatigue unit is fixedly arranged on the bearing platform and is positioned between the two vibration units; and the bearing platform is arranged on the longitudinal platform in a sliding mode and slides in a frame body of the longitudinal loading framework. The technical scheme of the invention solves problem that separate fatigue experiment table and vibration experiment table are used to complete fatigue experiments and vibration experiments in the prior art, so the two experiment tables have high building and investment cost and large occupied area, fulfills the aim of integrating the fatigue experiment table and the vibration experiment table, and has the characteristics of low building and investment cost and small occupied area.

Description

technical field [0001] The invention relates to the technical field of railway vehicles, in particular to a fatigue and vibration test bench and system. Background technique [0002] With the rapid development of "heavy and fast transportation" of my country's railway freight, the load and operating speed of railway vehicles are constantly increasing, and the operating conditions of the line put forward higher requirements for the performance of railway vehicles. In order to improve the design level of railway vehicles and ensure the safety of railway vehicle operation, reliability experiments in the research and development of "heavy-load, fast" railway vehicles are very important. Among them, the fatigue test and vibration test of railway vehicles are the main components of the reliability test. [0003] In the prior art, since the fatigue test and the vibration test are completed by separate fatigue test benches and vibration test benches, there are disadvantages that th...

Problems solved by technology

[0005] The present invention provides a fatigue and vibration test bench and system, which is used to solve the problem in the prior art that the fatigue test and the vibration test are completed by a separate fatigue test bench and a vibration test bench, so there is a relatively high investment cost in the construction of the two test benches. It has the defects of high height and large floor area; it realizes the purpose of integrating the fatigue test bench and the vibration test bench, has the characteristics of low construction investment cost and small floor space, and realizes the multifunctional combination of fatigue and vibration at the same time, increasing the Three-axle bogie vehicle vibration test
