In development project of a new car, the optimization of noise and vibration is very important to meet customer’s satisfaction. Resonance among items is one of reasons that cause vibration and noise in vehicles. In front-wheel-driven vehicles, “Goo” noise will occur when clutch pressure plate resonance frequency reach to transmission input-shaft resonance frequency in clutch partial engagement area in engine starting torque. In this paper, experiments to investigate main factors causing resonance at components of clutch and transmission were carried out.
