中文摘要:
      采用SolidWorks软件建立了4GXJ-2型电动割胶刀的传动机构模型,通过ADAMS软件对模型进行运动仿真和验证,使用SolidWorks软件中的simulation插件,对传动机构的关键部件强度进行有限元分析,结果表明:在扭矩分别为0.2 N·m、0.22 N·m、0.25 N·m的条件下,传动机构的运动曲线变化平稳且具有周期性,关键部件产生的最大应力为5.147 GPa,远小于材料的屈服强度220.6 TPa,而在形变方面没有明显变化。在样机与传统胶刀进行田间切割对比测试中,样机不仅可实现不撕老胶线割胶,提升割胶效率,而且在橡胶树的割面、耗皮、排胶等方面均具有接近于传统胶刀的割胶效果。
英文摘要:
      The transmission mechanism model of the 4 GXJ-2 electric rubber tapping knife was established by using SolidWorks software, and the model was simulated and verified by ADAMS software. The simulation plug-in in SolidWorks software was used to perform finite element analysis on the strength of the key components of the transmission mechanism. The results show that :Under the conditions of torques of 0.2 N·m, 0.22 N·m, 0.25 N·m, the movement curve of the transmission mechanism changes smoothly and periodically, and the maximum stress generated by the key components is 5.147×103 MPa, which is much smaller than the yield strength of the material 2.206×108 MPa, and there is no obvious change in deformation. In the field cutting comparison test between the prototype and the traditional rubber knife, the prototype not only realized the tapping without tearing the old rubber line, and improved the tapping efficiency, but also was close to the traditional rubber knife in terms of surface cutting,bark consumption, and rubber discharge of the rubber tree. The tapping effect.
