摘要：
A high-speed railway vehicle rigid-flexible coupling dynamics model including the flexibility of car body is built. Aiming at the car body vertical vibration, vertical semi-active control strategies are adopted in primary and secondary suspension system, respectively, and the influences of control strategies on ride quality are studied. Results show that both of the semi-active secondary suspension based on skyhook control law and the semi-active secondary suspension with continuous damping can effectively suppress the rigid vibrations of car body that lie in a relatively low frequency range, comparatively, the former can receive a better control result, but almost has no effects on the high frequency vibrations; The response frequency domain of semi-active primary suspension based on skyhook control law is wider, including 4~8 Hz which are the most sensitive vertical vibration frequencies for human body and the flexible vibrations in the range of 10~20 Hz. Results also show that semi-active primary suspension based on skyhook control law improves ride quality of car body most, and has little impact on wheel/rail interaction. © 2011 Journal of Mechanical Engineering.
