摘　　要：有限元法是一种基于变分原理的把连续体离散化的数值解法,具有适应性强、效能高等优点。应某型船改装需要,依据该船设备加装要求和甲板结构特点,按照有关规范,建立两型设备加装情况主甲板板架三维有限元模型,进行结构强度直接计算与校核,并据此提出基座加装位置及加强建议,实船加装效果良好。Finite element method is a numerical solution to discretization of continuum based on variational principle, which has the advantages of strong adaptability and high efficiency. According to the modification requirements of a certain type of ship, a three-dimensional finite element model of the main deck grillage with two type equipments installed is set up and the direct calculation and checking of structural strength are carried out in light of the installation requirements of the ship equipment, deck structure characteristics. Based on the above, the installation position of the base and the strengthening suggestion are put forward, and the installation result of the real ship is good.
