Summary:

Both multi-body dynamics and finite element tools are widely andeffectively used in automotive design. These tools have typicallybeen augmented with numerous custom extensions which greatlyenhance their utility. The capability of such tools hasconsiderable overlap in such areas as mechanical joints, contactdetection, and, of most interest here, linear (modal) structuralanalysis. By contrast, nonlinear structural effects, particularlylarge deformations, remain the domain of the nonlinear structuralanalysis tools. Such effects cannot easily be included when usingmulti-body dynamics analysis tools.Recently, a novel approach has been described through whichexisting, mature analysis codes can be combined into a singleanalysis tool that continues to leverage all of the validation,existing models and extensions of the component analysis codes. Asa demonstration of this approach, MSC's MD Adams (Adams), amulti-body dynamics code, and MD.Nastran/Sol(400) (Nastran), anonlinear structural analysis code, have been integrated.This paper describes the use of such an integrated analysis toolto perform a dynamic analysis of a twist-beam type automotive rearsuspension. The results will be compared to those generated fromthe same model using only the existing linear (modal) structuralanalysis capability of the multi-body dynamics analysis code
