Picking Mechanics Analysis and Simulation of Ingots on Cotton Picker

采棉机摘锭性能直接影响到采棉机田间作业的使用效率和经济性,结合摘锭在采摘过程中的工作状态,将摘锭简化为一悬臂梁进行力学分析,采用Solidworks软件建立了摘锭的三维实体模型,并对摘锭在脱棉过程中受到的弯曲和扭转变形基于Solidworks/SimulationXpress进行有限元分析,呈现了摘锭在此过程的应力、应变和位移分布,数值结果表明摘锭在外部环境变化引起载荷突变作用在其头部时,摘锭杆身变形较大,危险截面约在8-11个齿处,其结果为采棉机摘锭的结构设计提供参考。

The properties of cotton picker ingot directly affected efficiency and economy during picking process in cotton field. Combined with cotton picker ingot working state during picking process, simplified ingots as a cantilever beam and analyzed with mechanics method, the 3D solid model of ingot was established using Solidworks software, based on Solidworks/SimulationXpressfinite, the ben- ding and torsion deformation of ingot during removal of cotton process were investigated by finite element analysis method, the stress, strain and displacement distribution during removal of cotton process were determined. The numerical results showed that the ingot shaft caused a large deformation by changes in the external environment with load in the head, and dangerous section in 8 to 11 teeth, the simulated results could provide reference for structural design of cotton picker ingot.
