Strength and Modal Analysis of Thin-Shell-Structured Vessel with Rib Reinforcement

Abstract:

The Thin-shell-structured vessel with rib reinforcement is a key structure in petrochemical industry. For large scale and lightweight vessels design, it is essential to optimize the design based on the strength and modal analysis. In this paper a FEM model of Thin-shell-structured vessel with rib reinforcement was set up using Ansys software. It uses finite element programming to calculate its strength and modal numerically. The results indicate that the structure’s strength distribution, displacement distribution and situations about the first-six orders frequency of the vessel structure. Analysis of the calculation provides the numerical and theoretical supports of liquid vessels design under real working conditions.
