摘　　要：目的研究方罐盖注胶烘干机罩边机构在复杂应力作用下的静态和动态特性,并进行优化设计。方法通过Ansys Workbench建立罩边机构三维模型,应用有限元分析方法对上压板结构进行静态分析和模态分析;建立优化数学模型,对比分析优化前后结果。结果通过分析获得了优化前后的应力云图、变形云图以及模态振型图。优化后的上压板厚度减小了30%,宽度减小了7%,变形量等效应力增加,固有频率有所减少,质量减轻了约7.1 kg。结论经分析,罩边机构上压板的结构优化是合理的,在保证强度和刚度的条件下,减少质量并节约成本。This experiment researched the static and dynamic characteristics and made an optimization design of cover edge mechanism for square tin cover glue-injection and drying machine. The 3D model of cover edge mechanism was created by Ansys Workbench, and the method of finite element analysis was used for the static analysis and modal analysis of up plate structure. The optimization mathematic model was created and the analytical results before and after optimization were compared. Through the analysis, the stress and deformation before and after optimization and the modal vibration mode were obtained. The up plate thickness after optimization decreased by 30%, and the width reduced by 27%, while the equivalent stress deformation increased, the natural frequency reduced, and the quality decreased by about 7.1 Kg. The analysis showed the optimization of up plate structure was reasonable, and the quality was reduced and the cost was saved in the condition of ensuring the strength and rigidity.
