11809 励振される基礎上における剛体系のロッキングに関する研究(OS5 運動と制御(2),オーガナイズドセッション)

Abstract

The purpose of this study is to formulate a motion of rigid bodies system with unilateral contact problems by applying techniques of multibody dynamics and to analyze the issue of rocking conditions of the rigid bodies with slide contact or collision. The system is a coupled vibration system composed of three rigid bodies elastically supported by excited foundation. The differential algebraic equation is solved by the augmented formulation with Lagrange multipliers, using generalized coordinates and non-generalized surface parameters that describe the contact point. The influences of rocking mode and slip on the rocking motion are discussed.
