摘　　要：结合人体下肢生理特点和骑车运动特点建立了人车一体的连杆模型,并根据人体实际测量数据和经验公式获得模型参数;分析了骑行过程中的联动杠杆效应、骑行效率、骑行死点和死区现象;分别根据拉格朗日法和牛顿-欧拉法建立了人车模型的运动学和动力学方程,从而得到自行车运动等效曲柄转矩的转换过程以及各关节的受力和运动情况,为自行车骑行过程研究和设计工作提供理论基础.According to the physiological properties of human lower limbs and the cycling characteristics,a humanbicycle linkage model is built,and the model parameters are determined through body measurement and empirical formula.Then,the characteristics,such as the associated effect of bones,the cycling efficiency,the dead cycling point and the dead cycling zone,are analyzed,and the corresponding kinematic and dynamic models are established based on the Lagrangian and the Newton-Euler methods,which help to reveal the equivalent moment transformation for bicycle driving and to obtain the forces as well as the motions of human joints.The proposed method lays a theoretical foundation for the investigation and design of cycling process.
