The vibration transmissibility to the seated drivers has important influences on the human body comfort, health, and safety. To establish the dynamic equation for precondition of modal analysis, Newton-Euler method is usually used as the common study. However, this method is difficult to determine generalized coordinates belong to which natural frequency for linear system. On the other hand, by using transfer path analysis (TPA) as a new technique, it is possible to determine generalized coordinates of the vibration for the car machine affected the vibration of the car. The purpose of this research is to quantify the comfort level for driver's whole body vibration in passenger car based on ISO 2631-1 and to know the level of vibration on the car using transfer path analysis. This research tries to characterize the vibration effect of different sources (variation of the car machine) at idle condition. Human as the subjects are involved in this test. The results of this study show that low frequency vibration of the seat drivers affected to the ride comfort. Through TPA, the human body comfort can be evaluated using operational force by multiplying the natural frequencies of the car with the operational acceleration.
