Abstract

This paper describes an energy preserving integration method for the dynamic analysis of nonlinear multibody systems in the presence of nonlinear constraints. The aspects of finite rotation incrementation, discrete energy conservation and the most common constraint types are examined in detail. The application is made to several rigid body examples, including an intermittent contact problem.
