Automatic Control Technology for Vertical Vibration of Radial Bogie in High Speed Subway Operation
The vertical vibration of radial bogies in high-speed subway operating environments and specific frequencies reduces the stability of high-speed subway operation.To this end,a high-speed subway radial bogie vertical vibration automation control technology is proposed.Collect and zero mean the vertical vibration data of high-speed running subway radial bogies,use this data as the standard vibration data of radial bogies,and obtain their ODS working vi-bration modes from two perspectives:time domain and frequency domain.Design a fuzzy neural network controller based on the canopy damping model,and obtain the optimal vertical vibration control result of the radial bogie by inputting and training the ODS working vibration mode analysis results.The experimental results show that the pro-posed method can effectively control the vertical vibration of the radial bogie and improve the vertical stability of the subway body.
