摘要
对用于辅助下肢瘫痪患者重新站立行走的下肢助行器的总体方案及其工作原理进行了设计与分析。根据人机工程学中的人体结构测量及结构几何关系确定了各杆长度。在CATIA中建立了助行器的三维样机模型,通过ADAMS进行了运动仿真分析,得到了助行器的速度、力矩等参数,并与正常人体步态参数比较,验证了机构设计的合理性和方案的可行性。
The overall program and working principle of the walking aid which was designed to assist patients with lower limb paralysis to walk again was analyzed in this paper. Dimensions of each rod were determined according to the data of human body structure measured by ergonomics and geometric relations of the mechanism. A three-dimensional prototype model of the walking aid was established in CATIA. Motion simulation was carried out on mechanism in ADAMS. Parameters as velocity, torque and etc. of the walking aid were determined, which were compared with normal gait parameter of healthy human, both the design rationality and the feasibility of scheme for the mechanism was validated.
