In the present work, the biodynamic response behavior of seated human body subject to vibration in vertical direction have been extensively examined. The biodynamic response parameter of seated human body have been analyzed in terms of apparent masss (AM).The AM describe “to –the -body”force motion relationship at the interface of huma and seat. The present work proposed the six degrees of freedom (6-DOF) analytic biodynamic model of the seated human posture with the backrest in the vertical vibration direction to study the biodynamic response of various mass, stiffness and the damping coefficient. Field test were carried out using a TATA Nanocar to verify the vibrational comfort. The tests were carried out on different surface and the at different speed using Fast fourier transform (FFT) analyuzer. Acceleration were measured on both seat and head and the related calculation were done using MATLAB. This paper will help to analyze and provide the vibrational comfort to the car driver and the passangers on different road conditions.
