Methods for vibration damping in campus transportation vehicle

摘要

PROBLEM TO BE SOLVED: To improve active vibration damping of torsional vibration centered around a vertical axis of a yard conveying vehicle equipped with a mast.;SOLUTION: At a first step, vibration is detected by at least one vibration sensor and a vibration signal is transmitted to a control means capable of controlling a left side tilt cylinder 5 and a right side tilt cylinder 6. At a second step, the vibration is actively damped by controlling the left side tilt cylinder 5 and the right side tilt cylinder 6 with the control means. At this time, the control of the left side tilt cylinder 5 and that of the right side tilt cylinder 6 are respectively performed in an independent and separate manner and the torsional vibration centered around the vehicle vertical axis H is actively damped.;COPYRIGHT: (C)2010,JPO&INPIT
