Abstract
This paper presents the CAE technique to estimate the dynamic stress in a vehicle structure at an early stage in the vehicle design process, using modal stress superposition. Dynamic joint reaction forces are obtained by flexible multibody dynamics simulation using DADS. Stress influence coefficients are computed through the inertia relief analysis using MSC/NASTRAN. A test vehicle was run over a zigzag bump course with a constant speed of 40km/hr, and the results of the numerical analysis were compared to those of the test.
