This study aims to investigate a possibility of a 3-D human model constructed by using FEM to simulate the dynamic behaviour of human body seated in such as a car seat. The configuration of the FEM model and the properties of the finite elements composing the human model were empirically defined through trial-and-error method. Firstly, the dynamical behaviours of the FEM model under periodic vibrations were simulated with harmonic analysis to compare with the actual behaviours experimentally measured under the same vibration conditions. Next, the same FEM model also was applied to transient response analysis to compare the simulated results with the actual behaviours measured in the actual running test of a car. As a result, it was clarified that the dynamical behaviour of the upper parts of the human model were almost consistent with the actual behaviour, while the behaviour of the lower parts were quite different to the actual lower parts behaviour.
