等速度トラッキング運動中の筋粘弾性の調節

Abstract

An equivalent visco-elastic coefficient change of the in-vivo muscle in the constant tracking motion is investigated. The tracking experiments in a constant velocity has been made on human wrist joint with elastic load. A vibration frequency change of the tracking error is analyzed by the FFT method. And simulation by control model of a neuro-muscular system of human was made, then it made sure that the vibration frequency increase proportionally not only an elastic coefficient but also a viscous coefficient. By the experimental results, a following conclusion was got that an adjustment of the equivalent visco-elastic coefficient is depended on functions of higher motor control centers.
