目的 设计空间运动轨迹爬行训练装置,该装置能够实现通过转动轮盘带动上肢把手做椭圆运动,同时带动腿部支撑绕一个可做直线往复移动的点做30°~0°之间的往复摆动,从而可辅助使用者完成整个爬行运动。方法 首先运用SolidWorks对装置的结构进行三维建模;然后通过SolidWorks Motion 对整个装置进行运动学仿真,并通过计算完成动力学分析;最后从SolidWorks将主要受力部件导入ANSYS Workbench进行静力学分析。结果 与结论 设计的空间运动轨迹爬行训练装置可以辅助使用者完成预定的爬行运动,并且关键部件的强度校核满足强度要求。
Objective To design a space crawl training device. This device could achieve oval movement by rotating the wheel to drive the handle of the upper limb. At the same time, the leg support is driven to rotate about 30 degrees to 0 degrees, which can assist the user to complete the entire crawling. MethodsThe structure of the device was modeled using SolidWorks. Then the whole device was simulated by using SolidWorks Motion, and the dynamic analysis was completed by calculation. Finally, the main force components from SolidWorks were imported into ANSYS Workbench for static analysis. Resultsand ConclusionThe designed space trajectory crawling training device can assist the user to complete the scheduled crawling movement, and the strength checking of the key components meets the strength requirements.
