Abstract

In studying of the attenuation of high-speed railway vehicle lateral vibration, traditionnl skyhook damping control methods are designed to reduce body vibration. Althoughtt the vehicle lateral vibration is reduced , the bogie and wheelset lateral vibration increases, which may lead to vehicle derailment when the vehicle running at a high speed,the operation safety is also reduced. In order to solve the problem above, A single trailer vehicle model was established in the Adams/Rial.Combining the skyhook control with groundhook damping control,the mixed damping control was applied to reduce locomotive body lateral vibration. The results show that, mixed damping control consides both the high-speed railway vehicle comfort and safety, having better comprehensive performance.
