Analysis on Strength, Stiffness and Stability for Shippment Structure of Hull Subsection

Abstract:

In allusion to the safety problems of the shippment structure of hull subsection at area B in a Shipyard Co., Ltd., Guangdong, in this paper, a solid model for a proposed shippment structure of hull subsection was established by using a finite element software ANSYS which is a common software, the internal force (stress), deformation and stability of components under various actual working conditions were calculated, and then the checks of strength, stiffness and stability were performed on the basis of the national regulations. The results show that both strength and stability can meet the safety requirements of operation, but stiffness is insufficient, because the horizontal displacement of steel pillars in shippment structure oversteps the specified value of the national standards of China. The conclusion provides a theoretical foundation for the safety use of shippment structure of hull subsection and the optimization and improvement of the structure.
