Estimation of Human Motion Using Simplified Trunk Model

抄録

Recently more and more small-sized vehicles like a personal vehicle for small-group have been studied. As the mass of small-sized vehicle is similar to that of occupant, coupling behavior between them is important compared with conventional vehicle. Therefore, it is necessary to developing small-sized vehicle with a consideration to the dynamics of the human body riding on a vehicle. In this research, numerical simulation of human body dynamics on a vehicle was conducted. Generally, a human model is often simulated whole body in numerical simulation. However, whole body model has multiple degrees of freedom and property. Moreover, the influence of parameters of human is uncertainty and it is difficult to set accurate parameters. In this paper, the dynamics of only trunk of the human body which has little degrees of freedom on a vehicle was studied. Thus, these parameters of human motion control are identified from result of experiment and the simulation model. Furthermore, human motion is considered from characteristics of parameters which gained.
