Application of finite element model building and analysis in aerospace shell structure

Abstract

Shell parts are widely used in various aerospace products. Whether the design is reasonable will directly affect the product effect. According to the actual structure, the application of ANSYS software to the finite element modeling and analysis of shell parts can provide powerful theoretical analysis and guidance for future structural design. Taking the desulfurization tower as an example, common loads such as gravity load, internal pressure, wind load and seismic load are applied. The stress analysis, strength check and stability check of the desulfurization tower are completed, and the results meet the design requirements.
