Influences of Sitting Posture on Vibration Characteristics of the Human Body (Experimental Investigation) Shuji NISHIYAMA, Fumio TAKEDA and Tooru TAKESHIMA We present the influences of sitting posture on vibration characteristics of the human body in a moving vehicle. The vibration characteristics of a seated human have been measured with both sinusoidal and random vibration in the vertical and fore & aft directions at frequencies up to 20 Hz. Measurement points on the body are the head, chest, hip, thigh, and shin. Six subjects were studied used to elucidate the factors (angle of seat cushion and of seat back) that may affect human dynamic behavior. It was found that the sitting posture exerts a serious influence upon human dynamic behavior. Some results are presented in the from of parametric plots and tables. Key Words: Human Dynamics, Ride Comfort, Sitting Posture, Exprerimental Investigation. |
