可穿戴式腰背部治疗仪的机构设计及其运动学分析

Mechanical design and kinematic analysis of wearable lumbodorsal therapeutic instrument

针对可穿戴式腰背部牵引治疗仪的结构设计问题,提出了一种在使用舒适性、安全性、可靠性等方面具有突出效果的新型双平面铰接结构,并利用空间解析几何方法对治疗仪的机构进行了详细的数学推导,利用Matlab软件对样机进行了运动学仿真,了解其运动学关键指标,并对其运动空间和运动效果进行了分析和评价。在可穿戴式腰背部治疗仪样机实验台上对机构关键点的运动空间进行了测量,并由志愿者对治疗仪进行了实际穿戴测试。研究结果表明,该可穿戴式腰背部牵引治疗仪具有良好的治疗效果,其设计思路与分析方法可为其他产品的研发提供参考。

Aiming at the problems about mechanical design of thewearable lumbodorsal therapeutic instrument, a new dual plane hinge structure was put forward, which makes the instrumentmarkedly more comfortable, more reliable and safer. The detailed deduction of the mechanism was executed based on mathematical method. The prototype was simulated with Matlab, so that the kinematics of key indicators can be obtained and the movement space and effect can be evaluated.Based on experiments on the experiment table of wearable lumbodorsal therapeutic instrument, experiments of measuring and wearing by Volunteers were conducted.The results indicate thatthe treatment effect of this wearable lumbodorsal therapeutic instrument is satisfactory. The development of ideas and analysis method can be used for other products.
