Modeling vehicle suspension structural compliance at Ford Motor Company using a coupling of ADAMS and MSC/NASTRAN

McGuan, S.P. / Pintar, S.C.

At the Ford Motor Company, ADAMS is used to model vehicle components and system for a variety of purposes. Full vehicle models are used to study vehicle dynamics and chassis design effects on vehicle handling. In the Core Development Technology group at Ford, the Vehicle Dynamics New Methods C.A.E. section is analyzing vehicle dynamics, using an advanced data acquisition system and ADAMS vehicle models to correlate objective vehicle data with analytical model results. Part of the analytical model involves consideration of the vehicle body and suspension component compliances in addition to the tires and nonlinear bushings to determine their effect on vehicle handling. As an initial step, the rear suspension upper and lower control arms of a prototype vehicle design were modeled as compliant parts using MSC/NASTRAN and the ADAMS/FEA interface. The simulation maneuer consisted of a 60 mph double lane change maneuver to examine the component compliance effects of suspension geometry.
