摘　　要：当前我国老龄化速度进一步加快,老年人急需借助于一种能有效训练肩、肘和腕关节的上肢关节训练器械来辅助锻炼。而现有的上肢关节训练器械或机械结构复杂,或控制系统复杂,或功能比较单一,价格高昂也是其缺点之一,一般家庭难以承受。文中基于NX和CATIA设计了一种家庭用末端牵引式新型多功能上肢关节训练器械,确定了训练器械关键设计参数取值变化方式和方法,实现了圆弧曲线运动、近似椭圆曲线运动和圆周曲线运动等多种运动形式,并着重对上肢关节训练器械重要设计指标:圆弧曲线运动角度θ_(a)、角速度ω_(a)、近似椭圆曲线运动角度θ_(b)、角速度ω_(b)、圆周曲线运动半径r_(c)和角速度ω_(c)进行了虚拟样机数值分析和人机工程学数值分析。分析结果显示,人体上肢各关节活动度均在手臂ROM范围之内该结果为上肢关节训练器械物理样机的试制提供了重要的参考依据。Currently,with the ever-aging population,senior citizens are badly in need of upper-limb joint training devices,through the shoulder,elbow and wrist joints are trained effectively to assist exercise.However,the current upper-limb joint training devices have such disadvantages as complex mechanical structure,complicated control system,relatively simple function,and high price.Thus,it is difficult for ordinary families to afford them.In this article,with the help of NX and CATIA,efforts are made to design a new family-oriented end traction multi-functional upper-limb joint training device,work out the method of changing the value of the key design parameters,and realize many kinds of motion,such as arc curve motion,approximate elliptic curve motion,circular curve motion.In addition,with the focus on the important design indicators of the upper-limb joint training device,such as arc curve motion angle θ_(a) and angular velocity ω_a,approximate elliptic curve motion angle θ_(b) and angular velocity ω_b,as well as circular curve motion radius r_(c) and angular velocity ω_c.Both the virtual-prototype numerical analysis and the ergonomics numerical analysis are carried out.The results show that the degree of motion of the upper limb's each joint is within the arm ROM range.This study provides important reference for trial production of physical prototypes of upper-limb joint training devices.
