The Optimization of the Structure of Bulk Chemical Hull Based on MSC.Patran/Nastran

Abstract:

The optimization of the structure of bulk chemical hull (BCH) is derived by the finite element modeling (FEM) which is obtained by Patran and Nastran. In this paper, first of all, a new type of ship, BCH, is introduced. Then, the optimal scenario in theory is indicated by researching the transverse section of cargo holds of an ordinary BCH. And the FEM of the cargo holds of this ship is analysed, including the modeling, the load and the figures of stress and strain. The final conclusion would be obtained by comparing of the results which could verify the assumption forenamed. The simplification of the design is contributed by the new concepts and powerful capabilities of modeling of Patran and Nastran which improved the efficiency of ship designers.
