Abstract

In the study of vehicle riding comfort, the attenuation of vibrations transmitted from the road surface to passengers is an important topic for minimization of the discomfort level. So, how to identify the vehicle suspension model is another important issue in addition to the mathematical human model for research to enhance the comfort level of passengers. In this research, two kinds of vehicle models (2- and 3-D model) were systematically analyzed, and two systems of equations of motion (EOMs) were established for two different road surfaces. In this case, the passenger was considered as a driver. Finally, a numerical program is formulated in mathematical 4.0 to evaluate the impact of vibration on driver. The simulation results showed that, the 2-D model was restricted to the analysis of uniform road surfaces with the same input to both left and right tires. The 3-D model was recommended for analyzing the impact of vibration on passengers due to unevenness in the road.
