摘要
介绍了耙齿式残膜回收机的工作机理,通过对收膜工艺要求和弹齿的受力分析,得出弹齿最佳入土工作角度的区间及弹齿曲率半径大小对残膜滚落性能的影响,从而确立耙齿最佳排列方式。通过分析耙齿工作中所有可能受到载荷,计算出弹齿的最大载荷,利用ANSYS有限元软件仿真分析得出弹齿的应力和位移分布图,找出最大受力点和最大形变量,为后续弹齿优化设计奠定基础。
This paper introduced the working principle of tooth type residual film recovery machine, through analyzing the stress of elastic claw. Eliciting the best buried working angle interval of tooth and Influence of curvature radius of tooth rolling performance of plastic film, establish the best arrangement of tooth. Analysed the load of rake tooth in working, used ANSYS finite element software simulation analysis of the stress map, to find the point of maximum force and maximum deformation, optimization. and displacement of the elastic tooth distribution lay the foundation for the subsequent elastic tooth
