【摘要】：假肢膝关节是假肢最重要的结构,对假肢性能具有至关重要的影响。从仿生性角度出发,提出一种新型假肢膝关节结构。以踝关节轨迹作为步态评判标准,建立机构的运动学模型。论述模型结构的优化原则、目标函数以及约束条件,运用LINGO软件编程对模型中的尺寸参数进行优化。将优化后的结构模型运用ADAMS进行仿真分析,验证模型及优化的正确性。仿真结果表明,运用设计的新型假肢膝关节的假肢能够较好地模拟正常人行走的踝关节轨迹,具有较好的行走步态。
[Abstract]:The artificial limb knee joint is the most important structure of the artificial limb, and has a vital effect on the performance of the artificial limb. A new type of artificial knee joint structure is proposed from the angle of bionics. The kinematics model of the mechanism is established with the ankle trajectory as the standard of the gait evaluation. The optimization principle, objective function and constraint condition of the model structure are discussed, and the dimension parameters in the model are optimized by using the LINGO software. The optimized structural model is simulated and analyzed by using ADAMS, and the correctness of the model and optimization is verified. The simulation results show that the artificial limb of the new type of artificial knee joint can better simulate the trajectory of the ankle joint of the normal person, and has better walking gait.
