基于CATIA的水果采摘器运动模型参数化建模方法研究

The Parametric Modeling Method Study of Fruit Picking Motion Model Based on CATIA

采用CATIA设计并制作一种角度自调式水果采摘器。利用CAITADMU模块,完成内剪式剪刀机构主运动剪刀的运动仿真,输出内剪式剪刀机构相互运动结合点的曲线;利用CATIA二次曲线开发功能,完成从动剪刀片的运动结合处滑动槽设计,将虚拟仿真技术与机构运动分析有效结合。通过实物验证了该采摘器机构运行平稳,为广大果农采摘树上水果提供了一种有效采摘辅助工具,具有一定推广价值。

A fruit picking device which could adjust certain angle are designed and producted with CAITA software.Based on CAITA DMU module,the motion simulation of main movement scissors which are included in the shear mechanism with inside shearing style was finished.The mutual movement curve of combining point of shear mechanism was also exported.Using the secondary curve development function of CATIA,the sliding groove design of moving junction of driven shearing blades was finished,which combined the virtual simulation technology with effective mechanism motion analysis.Through the physical verification,the picking device works steadily,which provides an effective auxiliary picking tool for orchardman when picking fruits in the tree.The fruit picking device has had a certain application value.
