Short summary
A multi-degree-of-freedom dynamic vibration absorber (MDOF DVA) to suppress the vibration of the car body of high-speed trains is proposed. The MDOF DVA is installed under the car body, the main vibration frequency in each DOF of which is designed as a dynamic vibration absorber for lateral motion, bouncing, rolling, pitching, and yawing of the car body. The design principle of multi-DOF dynamic vibration absorption is analyzed by combining the design method of single DVA and genetic algorithm.
