出渣门快开结构的有限元分析及评定

Finite Element Analysis and Evaluation of Slag Door Quick Opening Structure

摘要: 利用ANSYS软件对出渣门快开结构进行有限元分析，根据国家新颁布的压力容器分析设计标准“GB/T 4732-2024”进行应力和疲劳评定。并对盖法兰和垫块啮合部位是否发生滑脱进行了非线性接触分析，得到了垫块接触面上的法向和切向摩擦力。结果表明，该结构满足应力限值要求，且盖法兰和垫块之间不会发生滑脱。旨在为工程设计中的快开结构有限元分析和评定提供参考。

Abstract: The finite element analysis is performed by ANSYS software for the slag door quick-opening structure, and stress and fatigue assessments are carried out according to the newly standard of “pressure vessel design by analysis—GB/T 4732-2024”. Moreover, non-linear contact analysis is carried out to determine will the meshing part between cover flange and sealing gasket slip, and the normal and tangential friction on the contact surface of the sealing gasket is obtained. The results show that the structure meets the requirements of stress limits and there is no slippage between the cover flange and the sealing gasket. It aims to provide reference for the finite element analysis and assessment of the quick-opening structure in engineering design.
