Abstract: In this paper a 17-degree of freedom (dof) human-seat system is developed using anthropomorphic modelling and the model is coupled with a 7-degree of freedom of a typical small passenger car to study the dynamic response of human driver due to vehicle vibrations. The coupled model is analysed by MATLAB simulation for ride dynamic behaviour of human driver under harmonic input excitation in the frequency range of 0-40 Hz. The ride behaviour in terms of vertical accelerations of different body segments of the human driver is compared for ride comfort using ISO-2631 standard. Further parametric analysis is carried out to improve the ride comfort of the human driver.
