Dynamic Analysis Of Constrained Nonlinear Multibody Systemswith Intermittent Contact.

Abstract

The present work deals with the dynamic analysis of flexible, nonlinear multibody systems
undergoing intermittent contact. The contact event is assumed of finite duration and the contact forces are
computed during the simulation. Two kinds of contacts are considered: rigid contact condition, treated
by using the slack variable technique, and flexible contact, treated by using suitable phenomenological
laws that relate the contact forces and the inter-penetration between bodies. The work is developed within
the framework of an energy preserving time integration scheme, that provides unconditional stability for
the kind of systems analyzed in this work.
