Automotive Powertrain Mounting System Design Optimization 2008-01-0879

Automotive powertrain mounting system design must balance three primary tasks: powertrain movement, powertrain rigid-body dynamic behavior, and vibration isolation. The design tool developed in this paper utilizes multi-body software and a genetic algorithm optimization routine to meet targets for mounting system stiffness, damping, attachment angle and geometry. Constraints on the optimization routine protect for drivability and NVH concerns, all at a significant savings in design resources.
