基于ANSYS的油茶果脱壳装置传动系统设计及仿真OA
Design and Simulation of Transmission System of Camellia Oleifera Fruit Shelling Device Based on ANSYS
目前油茶果脱壳大部分以人工脱壳为主,虽有部分机械化方法脱壳,但是存在能耗高、效率低、用途单一等缺点.面对我国油茶产业的快速发展,远不能满足生产需求.因此,研制具有分级脱壳清选一体的油茶果脱壳装置.并对此装置的传动系统进行设计及其脱壳主轴进行有限元静态分析和模态分析.静态分析表明:脱壳主轴总变形为0.012 5 mm;最大等效应力为18.695 MPa;扭转角度为0.057°,结果满足脱壳主轴的设计要求.经模态分析表明:脱壳主轴在固有频率为330.77 Hz时形变最大,且转速为19 188 r/min时存在共振现象,但转速远大于工作转速,故所设计的装置传动系统合理.研究结果可为后续与油茶果相似的坚果类物料提供参考.
At present,most of the hulling of camellia oleifera fruit is done manually.Although some mechanical hulling methods are used,there are some shortcomings such as high energy consumption,low efficiency and single use.Facing the rapid development of camellia oleifera industry in China,it is far from meeting the production demand,so a hulling device with grading hulling and cleaning is developed.The transmission system of this device is designed,and the finite element static analysis and modal analysis of its main shaft are carried out.The static analysis shows that the total deformation of the hulling spindle is 0.012 5 mm;the maximum equivalent stress is 18.695 MPa;the twist angle is 0.057°,and the result meets the design of the spindle.According to the modal analysis,the deformation value of the hulling spindle is the largest when the natural frequency is 330.77 Hz,and there is resonance phenomenon when the rotating speed is 19 188 r/min,but the rotating speed is much larger than the working speed,so the transmission system design of this device is reasonable.It can provide reference for subsequent nut materials similar to camellia oleifera fruit.
