Abstract：The engine cooling module (CRFM) is one of the main sources of noise and vibration for idling automobile. This paper focuses on the vibration of a V6 engine cooling module and its influences on the steering wheel numerically and experimentally. The numerical model of CRFM vibration utilizes energy decoupling and Newmark-Beta methodology, taking chassis and cooling fan vibration into account. The optimization of CRFM isolators is based on hybrid genetic algorithm and validated both numerically and experimentally.
