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SolidWorks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SolidWorks 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 crawl spinal rehabilitation training apparatus was described.The crawling machine could realize the passive form of kneeling crawling, climbing crawling, prone to crawl, waist swinging and other multiple crawling training mode.Crawling movement has very good training effect on the spine.According to the movement of crawling，the action was designed. The whole structure of the training instrument was reconstructed with 3D by using SolidWorks. The kinematics and dynamics of the training equipment were analyzed, and the kinematics and dynamics simulation were carried out with SolidWorks Motion.Finally，the main force component was carried on the static analysis with the finite element analysis software ANSYS Workbench.By motion simulation, the three-dimensional model could achieve a variety of scheduled movement patterns, and the strength of the key components checked could meet the strength requirements.The training instrument movement pattern is diverse and the design is reasonable, the material intensity is suitable. The design has certain feasibility.
