内容記述
The incident of the fall accident in use public transport is higher than that of in other place,because of the floor of the vehicle is exited. Knowing the influence of the rolling,pitching and yawing of the ship to the fall is important. In this paper,the human body is modeled by triple inverted pendulum. The model that subjected to the acceleration disturbance measured on ship is stabilized by optimal feedback control. Temporal change in the posture of the triple link model on sagittal plane have been simulated. Joint torques for maintaining a standing posture are obtained from the simulation. Monitoring the movement of the center of gravity due to posture change,we investigated the relationship between the joint torques and the center of gravity inside and outside a stable area of the base of support. We considered the necessary condition for fall-prevention strategy by using the obtained results.
