Abstract

A method for the systematic formulation of the equations of motion for multibody systems containing rigid and flexible bodies is presented. The method of joint coordinates for deriving the minimum number of equations of motion is utilized for rigid bodies, and the finite element method is employed for flexible bodies. The equations of motion for flexible bodies are simplified in several steps: lumped mass assumption, static condensation, and modal superposition. The combined rigid and flexible body formulation can be used to simulate dynamic response in a variety of applications, such as ride handling, rollover, and crash analyses of vehicles; space structure analyses; and biomechanical problems.
