The process of adopting speed limit to ensure operation has no other measures, and how to ensure the operation safety and comfort of the vehicle under certain wind speed condition is an urgent problem.
At present, research on rail beams at home and abroad mainly focuses on vertical rigidity of the rail beams, transverse rigidity of the rail beams is seldom researched, the transverse rigidity of the rail beams also can influence safety and stability of vehicle operation, and meanwhile, transverse larger vibration also can influence safety and integral line state of a rail beam system.
