Damping device for train


PURPOSE: To effectively reduce low-frequency region large-amplitude vibration affecting the position holding of passengers by supporting the compartment space of a train floatingly on a body through spring mechanism, and damping actively through an actuator. CONSTITUTION: A toilet-washroom booth 28, a part of a compartment space, is floatingly supported on a body 18 through spring mechanisms 30. At an intermediate part between the spring mechanisms 30, an actuator 40 is disposed between the toilet-washroom booth 28 and the body 18. The actuator 40 generates reciprocating force according to the cycle of relative displacement between the body 18 and the toilet-washroom booth 28. COPYRIGHT: (C)1992,JPO&Japio
