Abstract : Based on transfer path analysis(TPA) theory, the driver floor's vertical vibration acceleration which was caused by engine excitation was taking under the condition of idle and 50 km/h in the city. The method and procedures of TPA were amplified. The dominant transfer path which has influence on ride comfort was identified, while the mount transmissibility was analyzed. The results show that the right mount excitation influences the driver floor's Z acceleration most and its transmissibility is also not well. The isolation performance of right mount needs to be improved for ameliorating ride
