基于逆向工程的D型打结器重构与运动仿真

打结器是方草压捆机的关键核心部件之一,直接影响打捆机的成结效率和捆形质量。以D型打结器为研究对象,基于逆向工程技术对其进行三维重构,进而对重构零件的关键工作曲面进行了偏差分析,发现所有关键工作面90%以上的区域达到了精确等级以上。基于Solidworks软件实现了重构部件装配,并进行了运动仿真研究,获取了卡线轮、打结嘴、脱绳杆角速度和驱动齿盘角位移数据,分析了卡线轮、打结嘴、脱绳杆与捆绳打结运动关系,为优化D型打结器提供了基础数据。

Reconstitution and Motion Simulation of D-bale Knotter Based on Reverse Engineering

D-bale knotter is one of the key parts of square baler, which influences the efficiency and quality of baler. Based on reverse engineering, D-bale knotter was reconstituted and the accuracy of working surfaces was analyzed. The results showed that more than 90% domain for all the working surfaces can achieve the precise level above. Reconstruction parts of D-bale knotter were assembled and then simulated by using the software Solidworks. The angular velocity and displacement data of twine holder, bill hook, wiping arm, and driving dentate disc were obtained and the movement relationships of these parts were further analyzed. This study will provide basic data for the optimization of D-bale knotter.
