【摘要】：设计出一款多态脊柱康复爬行训练仪。该爬行仪可实现被动形式下的跪撑爬行、攀高爬行、俯式爬行、扭腰摆动等多种爬行训练模式。爬行运动对脊柱有很好的锻炼效果,根据爬行运动设计要实现的动作,利用Solid Works对训练仪整体结构进行三维建模,对训练仪进行运动学和动力学的理论分析,并结合Solid Works Motion进行运动学和动力学仿真。最后通过有限元分析软件ANSYS Workbench对主要受力部件进行静力学分析。通过运动仿真,三维模型可以实现各种预定的运动模式,而且对关键部件进行的强度校核满足强度要求。该训练仪运动模式多样且结构设计合理,选材强度合适,具有一定的可行性。
[Abstract]:A polymorphic spine rehabilitation crawling training instrument is designed. The crawler can achieve the passive form of kneeling crawling, climbing high crawling, bent crawling. Writhing waist wobble and other crawling training modes. Crawling exercise has a good effect on the spine, according to the crawling movement design to achieve the action. The whole structure of the training instrument is modeled by Solid Works, and the kinematics and dynamics of the training instrument are analyzed theoretically. The kinematics and dynamics are simulated with Solid Works Motion. Finally, the finite element analysis software ANSYS is used. The statics analysis of the main force components is carried out by Workbench, and the motion simulation is carried out. The 3D model can realize a variety of predetermined motion modes, and the strength of the key components can be checked to meet the intensity requirements. The training instrument has a variety of motion modes, reasonable structure design and suitable material strength. Have certain feasibility.
