Abstract

The invention relates to the field of computer aided design, in particular to a ship structure fatigue analysis and research method, which comprises the following steps of: modeling a ship structure by using a finite element method to obtain a ship grid model; loading a wave load to the grid model for load analysis; and modifying the local structure which does not meet the requirement based on a load analysis result. A quality model is established in a finite element mode, the ship can be better analyzed, then a wave load is loaded to evaluate the fatigue degree of each part of the ship, and finally areas which do not meet requirements can be modified based on an evaluation result, so that the anti-fatigue degree of the ship can be conveniently improved, and the anti-fatigue performance of the ship is improved. The service life of the ship is prolonged.

Description

technical field [0001] The invention relates to the field of computer-aided design, in particular to a research method for ship structure fatigue analysis. Background technique [0002] During the operation of the ship, it will continue to be impacted by wave fluctuations, which can cause periodic, indeterminate external forces on the surface of the bottom of the ship to deform. This will greatly affect the strength of the ship, so it is necessary to analyze the fatigue degree of the ship structure. However, the existing analytical methods are inconvenient to detect ships. Contents of the invention [0003] The purpose of the present invention is to provide a ship structure fatigue analysis research method, aiming at detecting the ship more conveniently. [0004] In order to achieve the above object, in the first aspect, the present invention also provides a ship structure fatigue analysis research method, including: [0005] The ship structure is modeled with the finit...
