Design Support Methods for Comfortability in Riding of the Wheelchair Transporting Apparatus (1st Report, Vibration Simulation Model on the Human-Wheelchair System)

In the present study, we developed a simulation model of human-wheelchair system in order to support the design of the wheelchair transporting apparatus. First, we modeled the system as a seven-D. O. F. dynamic model of two dimensions. This model has some parameters of unknown value. Secondly, we conducted modal analysis to clarify the modal parameters on the system. Thirdly, we solved the equation of motion including the modal parameters. As a result, the model was identified because the unknown values of parameters on the model were obtained. Finally, model simulations were practically performed by varying the physical parameters. It is found that the identified model was effective for improving comfortability in riding of the wheelchair transporting apparatus.
