本研究的目的是寻找自行车骑行系统的最佳设计参数值(曲柄长度,骨盆倾角,座位高度和曲柄旋转速率),以最大限度地提高人体下肢肌肉在骑自行车时的功率输出。将人体下肢建模为一个由五个刚体组成的平面系统,由四个光滑的销关节连接,由七个功能肌群驱动。假定肌肉的行为符合希尔方程的一种改编形式。研究了平均功率与设计参数的关系。研究了各肌群的瞬时功率,并分析了两个看似对立的肌群的同时活性。一次全踏板旋转的平均峰值功率约为1100w。与此峰值功率输出相对应的上半身位置稍微倾斜,踏板速度为155 rpm,公称曲柄长度为170 mm。
The purpose of this study was to find the optimal values of design parameters for a bicycle-rider system (crank length, pelvic inclination, seat height, and rate of crank rotation) which maximize the power output from muscles of the human lower limb during bicycling. The human lower limb was modelled as a planar system of five rigid bodies connected by four smooth pin joints and driven by seven functional muscle groups. The muscles were assumed to behave according to an adapted form of Hill's equation. The dependence of the average power on the design parameters was examined. The instantaneous power of each muscle group was studied and simultaneous activity of two seemingly antagonistic muscle groups was analyzed. Average peak power for one full pedal revolution was found to be around 1100 W. The upper body position corresponding to this peak power output was slightly reclined, and the pedalling rate was 155 rpm for a nominal crank length of 170 mm.
