论文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。并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较为全面的理论基础。最后根据各个分析结论进行新型自行车设计的方案构思与展望。

According to physiological and cycling characteristics, a model of human-bicycle was built, and its parameters were obtained from body measurement and empirical formula. Through this model, the characteristics such as associated effect of bone, cycling efficiency, dead point and dead zone of cycling were analyzed. After that, the methods of Lagrangian and Newton-Euler were adopted to establish the kinematical and dynamical models and obtained the equivalent moment for bicycle driving as well as the forces and motions of joints. All that devoted to the theoretical basis for bicycle research and design.
