The purpose of this study is to formulate a motion of a rigid body with unilateral contact problems by applying techniques of multibody dynamics and to analyze the issue of rocking condition of the rigid bodies with slide contact. In order to deal with rocking motion with slide contact, we formulate for dynamics of simple rigid body system with unilateral contact model. Judgment for occurrence of the contact between a rigid body and a base are applied. A planar motion of the rigid body system having a simple shape and both cases with and without slide are assumed. We analyze rocking motion of the rigid body including slide and frictional force. We solve the differential algebraic equation by augmented method with Lagrange multipliers, using generalized coordinates and independent variables which describe contact points. The influence of the frequency and amplitude of disturbance given to the base are discussed.
