Summary:

Multidisciplinary analysis that involves simulation of automotive models by carrying out multibody dynamics analysis for load extraction and then followed by inertial relief static analysis for prediction of structural results is commonly followed. Commercial Finite Element (FE) codes require that body loads coming from the multibody analysis be ignored when running the inertia relief analysis, which generates its own internal D'Alembert body loads. In such case, there is, however, a potential pitfall that although the equilibrium is established in the ensuing inertial relief static analysis, the internal body loads do not represent those from the multibody dynamics. This has the potential to produce incorrect results, especially when rotational body loads are very high. The author hereby proposes a methodology to overcome this pitfall to model the exact physics and get accurate results thereof
