Vibration transmission simulation model of a seated vehicle passenger

The research that is conducted to develop a comprehensive simulation for a seated passenger in a moving vehicle is a representation of the vertical vibration resulting from the bounce effect of the vehicle when it travels along the road with sinusoidal excitation at different speeds. Although extensive research has been conducted in this field of study, the existing analysis are conducted on either the suspension of vehicle or the human body and not both. In this paper, the simulation model consists of three sub-systems, namely, vehicle suspension, seat suspension and human body model in which the vertical vibration will be transmitted. By incorporating these sub-systems into the simulation, a causable relationship can be formed due to the linkage between the three sub-systems. The transmission of vertical vibration caused in this simulation provides a more realistic approach which can result to a better comparison to the real-life scenario. The results of the research would provide a better understanding on how existing passive suspension systems can be modified based on its parameters to improve the ride comfort of passengers. Furthermore, a more characterizable vibration response when comparing to real life scenarios can be obtained through the validation process.
