Abstract

The invention provides a test platform assembly for railway vehicle fatigue and vibration test. The test platform assembly includes a fixedly arranged support platform, a test platform slidably arranged on the support platform, a driving device, and a plurality of fastening structures, the top surface of the test platform is provided with an integration loading mechanism installing part, the bottom surface of the test platform is attached to the top surface of the support platform, the driving device is used to drive the test platform to slide on the support platform; and each fastening structure has a fastened state in which the test platform is relatively fixed to the support platform and a release state in which the test platform can slide with respect to the support platform. The test platform assembly can effectively solve the problem that the test bed in the prior art cannot meet the requirements of the overall fatigue and vibration test of the railway vehicle.

Description

technical field [0001] The invention relates to the technical field of railway vehicle testing, in particular to a test platform assembly for railway vehicle fatigue and vibration tests. Background technique [0002] In the prior art, fatigue and vibration tests for railway vehicles are usually performed separately for each component of the railway vehicle. However, the weight of each component of the railway vehicle is lighter than that of the vehicle as a whole, and it is generally sufficient to use a small test bench to fix the above-mentioned components separately. The small test bench can be moved and adjusted through the slider structure or the machine tool guide rail mechanism, and the fixed method after it is moved in place is fixed by the bolt pressure plate. However, if it is necessary to carry out the fatigue vibration test on the whole railway vehicle, the size and weight of the test bench of the railway vehicle are relatively large, and the above-mentioned smal...
