Title:
マリンプラットフォーム用アクティブサスペンション
Document Type and Number:
Japanese Patent JP2005518993
Kind Code:
A
Abstract:
An active suspension system is used to control the motion of a passenger seat in a high speed watercraft. A forward looking wave sensor is used in connection with a feed-forward wave impact shock predictor to determine characteristics of impending dynamic forces applied via the impact of the watercraft on waves. Information concerning the impending dynamic forces is used by a passenger seat suspension and control system to attenuate the shock effects on passengers, where such effects are characterized by large-amplitude, short-duration accelerations recurring at a low frequency and/or irregularly.
