Abstract
A railway vehicle vibration damping device includes an actuator interposed between a vehicle body and a truck and capable of exerting a control force; and a controller configured to obtain a target control force for reducing a vibration of the vehicle body based on a lateral acceleration of the vehicle body, and the controller includes a bandpass filter configured to extract a low frequency control force, which is a frequency component lower than a resonant frequency of the vehicle body, and a correcting part configured to correct a target control force based on the low frequency control force.
Claims4
A railway vehicle vibration damping device comprising:
- an actuator interposed between a vehicle body and a truck of a railway vehicle and capable of exerting a control force;
- and
- a controller configured to control the actuator by obtaining a target control force for reducing a vibration of the vehicle body based on a lateral acceleration of the vehicle body,
- wherein the controller includes
- a filter configured to extract a low frequency control force, the low frequency control force being a frequency component lower than a resonant frequency of the vehicle body in the target control force, and
- a correcting part configured to correct the target control force based on the low frequency control force.
