自動車シート振動の着座者への伝達特性に関する研究

抄録

In order to clarify the psychological stress by the seat vibration on its occupant in the vehicle, the vibration transfer characteristics from each part of the seat to the occupant were investigated. The experiment was conducted in an idling-state vehicle, and was investigated by applying the operational transfer analysis to the vibration measurement results of the seat and the occupant. As a result, it is clear that even when subjects with the same height and weight were seated on the same seat, the body position and vibration mode at which vibration was maximized were different, which causes a difference in psychological stress to them. It was also found that these differences may be caused by the difference in the characteristics of the center of gravity of the subjects.
