Abstract
This paper discusses a multidisciplinary design optimization of the engine system to improve the ride quality of a vehicle and to remove the possibility of the resonance between the powertrain system and vehicle systems. The driveline model attempts to provide practical support to engine mount development by providing sufficient detail for design modification assessment in a stable and efficient modeling environment. By applying forced vibration analysis for vehicle systems and mode decouple analysis for the engine mount system to design the engine mount, it is shown that improved optimization result is obtained.
