ABSTRACT
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 de-grees,which can assist the user to complete the entire crawling. Methods The 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. Results and Conclusion The 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.
