Research on Lateral Vibration and Load Sensitivity Reductions for Large‐Scale Complex Nonconservative Systems Using Rigid‐Flex Coupling Simulation Technique

Shock and Vibration, Volume 2024, Issue 1, 2024.
For large‐scale complex nonconservative systems such as high‐speed rolling stock, the rigid‐flex coupling simulation technique is one of the effective methods in reducing lateral vibration and dynamic load sensitivity. Since two uncertain influences of wheel spin dissipation are caused by wheelset yaw oscillations and alternative load path variation ...
