遠隔操作油圧ショベルにおける機体挙動フィードバックのための振動情報に関する考察

抄録

The productivity of widely-used tele-operated system is lower than that of operating actual excavator. One of the causes is lack of machine behavior information. Therefore, there is a possibility that work efficiency may be improved by realizing feedback of machine behavior information using a motion simulator seat. In this study, the subjective vibration magnitude was calculated by frequency correction, according to human perception characteristics, about the acceleration on the seat surface for the specific behavior of the hydraulic excavator. As a result, for the end-of-stroke impact of the attachment, it was found that the vibration in the lateral direction of the excavator is smaller than in the other direction. This suggests the possibility that the reproduction of the vibration in the lateral direction is not necessary for the machine behavior feedback.
