Analytical study on seated human models to improving better conditions for passengers

Abstract

In this research, a nine-DOF multi-body model was selected to discuss and compare to a four-DOF lumped-parameter model. In oder to contruct the mathematical models, Newton’s second law was applied to derive System equations of motion (EOMs). The frequency-domain method was selected as the solution technique to analyze the mathematical models. Each model was simulated and validated with the experimental data. The comparison of the experimental data with those off our- and nine-DOF model shown that nine-DOF model produced better matching in transmisibilities. The nine-DOF model was suggested in the simulation to improving better conditions for passengers.
