A multi-degree of freedom dynamic vibration absorber (MDOF DVA) to suppress the vibration of the carbody of high-speed trains is proposed. The MDOF DVA is installed under the carbody, the natural vibration frequency of which are designed as a dynamic vibration absorber for lateral motion, bouncing, rolling, pitching, and yawing of the carbody. A high-speed train dynamics model including an under-carbody MDOF DVA is established. Based on the virtual excitation method, the vibration control effect on each DOF of the MDOF DVA on the carbody is analyzed. Results show that the MDOF DVA can absorb the vibration of the carbody in multiple degrees of freedom.
