Abstract Dynamic model of the leg prosthesis plays an important role in the research of bionic artificial limb prosthesis.Aiming at the problem of bionic artificial limb prosthesis, the basic structure of the leg prosthesis was designed. The kneeanklefoot model was set up on Pro/E and the nonlinear dynamic model was presented, with the friction question between the joints considered. Finally, the simulation experiment was carried out on ADAMS, which testified the validity of the structure and the dynamic model by computer simulation．

基于虚拟样机技术的下肢假肢结构设计与仿真
下肢假肢动力学问题是智能仿生人工腿(intelligent bionic artificial limb prosthesis)研究领域中的重要内容．针对智能仿生人工腿,设计下肢假肢基本结构,运用Pro/E建立下肢假肢膝踝足关节模型,进行非线性动力学分析,并考虑了关节间的摩擦问题．最后,通过ADAMS虚拟样机技术,对人体行走步态进行仿真模拟控制,为下肢假肢、步行机器人研究提供了理论基础．
