102 下肢動作モデルを用いた自転車競技におけるペダリングメカニズムの動力学的解析(OS1-(1),OS1オーガナイズドセッション≪計算力学と数値シミュレーション≫)

Abstract

In this study, kinetic analysis system of pedaling mechanism was investigated to evaluate pedaling efficiency using lower limbs model. This system was composed of evaluation program for calculation for joint torque of lower limbs. The lower libs model consisted of three segments, the thigh, the lower thigh and the foot. From the lower limbs model, all position of lower limb segments and joint torques were calculated. Additionally, the relationship between the ankle angle and normal force was proposed. This relationship does not require the image-analysis software with the high-speed camera.
