MOTION AND VIBRATION ANALYSIS AND THE CONTROL OF AN ELASTIC VEHICLE USING AN EXTENDED REDUCED ORDER PHYSICAL MODEL

Abstract

This paper proposes a new modeling technique for motion and vibration in flexible structures. We call this modeling technique the 'extended reduced order physical model'. Because vibration is generally influenced by motion, it is necessary to analyze vibration and motion together. A new modeling technique can be used to represent both motion and vibration. The effectiveness of this modeling technique is confirmed by simulated as an elastic vehicle using a flexible rectangular plate. Two elastic vibration modes as well as the bouncing, rolling and pitching of the vehicle were controlled using the LQ control method.
