Abstract

This paper describes modelling aspects for the inclusion of linked rigid and deformable segment occupant models into an explicit finite element crash simulation code. The realistic modelling of dummy joints is crucial for the numerical simulation of occupant kinematics and dynamics during impact. Different models for dummy joints are available in programs based on Rigid Body Dynamics. A new approach for the modelling of joints in an explicit finite element (FE) code is presented. It combines the effectiveness of the rigid body joints with the advantages of uncoupled system equations. Examples are given to illustrate the function of the different joints. Comparisons with results from standard crash victim simulation programs, and correlations of actual sled test results with preliminary simulation results serve as a basis for validating the FE-joint models.
