Abstract : The fundamentals of the transfer path analysis (TPA) was introduced, the transfer paths from the road surface excitation through vehicle suspension and body to the acceleration of vertical vibration of the floor under the driver seat were analyzed using software LMS/TPA. The vehicle road test and the indoor hammering test were performed to elucidate the vibration transfer paths. The dominant transfer path in the suspension system that affects the vehicle ride comfort most was identified. The results show that the contribution of the rear point of the right lower control arm of the front suspen
