Abstract

In this study, we developed a six-degrees-of-freedom (6 DOF) mathematical human model that can quantitatively analyze the ride quality. The developed human model was connected with CarSim using MATLAB/Simulink in order to calculate human vibrational responses. With respect to the uncertainty parameter of the human model, its responses were verified comparing the computational results by generalized polynomial chaos (gPC) and monte carlo simulation (MCS) methods. It was confirmed that the computational cost as well as the results calculated by the gPC method showed adequate agreement with those obtained by MCS. Finally, a sensitivity analysis was also conducted calculating the mean and standard deviations as well as the ride comfort index based on the British standard, BS 6841.
