Finite Element Analysis on the Key Components of Sunflower Seed Removal Machine

  • 摘要: 机架作为葵花脱籽机关键部件,其结构设计合理与否直接关系着整机的安全性和可靠性。该文基于三维设计、分析软件对葵花脱籽机机架进行静力学分析和模态分析,通过SolidWorks 2019软件构建机架三维模型,借助Simulation插件对机架进行静力学分析,通过分析得出机架最大应力和应变均符合设计要求,机架最大应变1.96 mm。其次,借助ANSYS Workbench 2021对机架进行12阶自由模态分析,通过分析得出机架固有频率为67.03 Hz,机架固有频率大于电机运行频率50 Hz,整机运行时机架和电机不会发生共振,所研究内容可为葵花脱籽机结构优化提供参考。

     

    Abstract: Frame is a key component of the sunflower seed removal machine, and its reasonable structural design is directly related to the safety and reliability of the whole machine. Based on the three-dimensional design and analysis software, the statics analysis and modal analysis of sunflower seed removal machine frame is conducted in this paper. The three-dimensional model of the frame is built through the SolidWorks 2019 software, and the statics analysis of the frame is carried out with the help of the Simulation plug-in. It is concluded through the analysis that the maximum stress and strain of the frame are in line with the design requirements, and the maximum strain of the frame is 1.96 mm. Secondly, the 12 th order free modal analysis of the frame is conducted with the help of ANSYS Workbench 2021; it is concluded through the analysis that the intrinsic frequency of the frame is 67.03 Hz, which is greater than the motor operating frequency 50 Hz, so as to ensure that the frame and the motor will not resonate during the running time of the whole machine. This study can provide a reference for the structural optimization of the sunflower threshing machine.
