Finite Element Analysis of Surface Ship Hull Thin Section Lifting Scheme

Abstract

Aiming at the problems that the deformation of the thin plate segments of surface ships may damage the internal structure or lead to the inability to lift and close the ship, taking three typical thin plate segments of a ship as an example, the corresponding lifting plan is designed, the factors affecting the construction efficiency of the lifting equipment on the whole process of lifting them are discussed, the deformation of the three thin plate segments under different working conditions is calculated by using the finite element analysis method, and the temporary strengthening plan is proposed for the segments with oversized deformation. temporary strengthening scheme. The results show that the lifting solution is suitable for the weak structural strength of the thin plate segments of the hull and meets the requirements of the classification society lifting code, thus making the lifting operation of the thin plate segments of the ship hull more convenient and efficient.
