Abstract EN
This study focuses on the biodynamic responses of a seated human model to whole-body vibrations in a vehicle.
Five-degree-of-freedom nonlinear equations of motion for a human model were derived, and human parameters such as spring constants and damping coefficients were extracted using a three-step optimization processes that applied the experimental data to the mathematical human model.
The natural frequencies and mode shapes of the linearized model were also calculated.
In order to examine the effects of the human parameters, parametric studies involving initial segment angles and stiffness values were performed.
Interestingly, mode veering was observed between the fourth and fifth human modes when combining two different spring stiffness values.
Finally, through the frequency responses of the human model, nonlinear characteristics such as frequency shift and jump phenomena were clearly observed.
