[0066] The present invention will be described in detail below in conjunction with the drawings:
[0067] The high-speed wheel-rail relationship reliability test bed contains the track wheel motion device and the power bogie simulation loading structure that can accurately simulate the radial and axial loads and the impact of the track on the wheelset under the actual working conditions of the rail train wheelset. In addition to the state of motion under various motion conditions, the vibration of the rail vehicle wheel-rail during operation is truly reproduced, thereby ensuring the correctness and authenticity of the test results of the reliability parameters of the high-speed wheel-rail relationship of the high-speed train.
[0068] Refer to figure 1 , figure 2 , Figure 24 , The high-speed wheel-rail relationship reliability test bench includes the track wheel motion device 1 and the power bogie simulation loading frame 2. The orbital wheel motion device 1 includes a frequency-...
