摘　　要：传统方法构建的人体动力学仿真模型只能求解整体受力和发力参数,对各个关节驱动作用力矩的求解模型未提及。提出一种基于7连杆模型结构的人体下肢动力学分析模型,引入机械系统动力学分析用的ADAMS软件到人体动力学分析中,求解各种运动模式下人体下肢左右腿各关节驱动作用力矩。对人体运动Lagrange动力学方程式进行优化求解,得出详实的理论分析值和仿真数据,并进行对比分析。仿真实验表明,构建的单腿支撑和跑步运动模型下的人体下肢动力学分析模型,能有效准确地仿真计算出人体下肢全部关节的驱动力矩,仿真结果为分析人体最佳发力模式,指导和优化体育训练具有很好的理论参考价值。The traditional method of the human body dynamics model only solved the overall force and power parameters, but the detailed joints were not analyzed. The human lower limb dynamic analysis model was proposed based on 7 bar link-age model structure. The ADAMS software was used as the platform, and the joints driving torques were computed as the fi-nal results based on the optimal Lagrange dynamics equation. The detailed theoretical and simulation data were got. Simula-tion results show that the constructed models can calculate the drive torque of lower limbs effectively and accurately for all joints, it provides best force pattern, and it has important value in guiding and optimizing the sports training.
