| 摘 要： | 本文应用机构学、生物力学和流体力学等方面的理论，对气压膝关节大腿假肢进行了较为系统的分析和研究。在对实现假肢站立相稳定性和摆动相控制性分析的基础上，用平面多杆机构模拟大腿假肢的多中心膝机构，建立了该机构的力学模型，并进行了最优化方法设计；根据正常人体的步态数据，用气压控制装置来模拟假肢摆动相控制性，并达到良好效果；最后进行了假肢膝关节的结构设计。

| Abstract: | In this paper, the above-knee prosthesis with a pneumatic swing control knee joint has been designed with the theory of mechanisms, biomechanics and fluid mechanics. Based on analysis of the stance phase and the dynamic stability of the prosthesis, a planar multi-linkages is used as the poly-center knee mechanisms of the prosthesis, after given the mathematical medal of its. Then best structure parameters is given by using optimizing method. A pneumatic control device is used as swing phase control device of the AK prosthesis ,for matching with the step phase of usually man. The structure of pneumatic swing knee joint is designed in the end. |
