Optimal design method for ship inner shell plate

Abstract

The invention relates to an optimal design method for a ship inner shell plate, which achieves the purpose of obtaining the maximum ship cargo hold volume by parameterizing and labeling a ship inner shell plate and optimizing the shape and size of the ship inner shell plate in a design stage by using a swarm intelligence optimization algorithm. Under the condition that various maritime affair organization rules and classification society specifications are met, size constraints, stability constraints, draught constraints and navigation speed constraints of ships are comprehensively considered,and an artificial bee colony optimization algorithm, a particle swarm optimization algorithm, a genetic optimization algorithm and a differential evolution algorithm are used for carrying out optimization calculation with the maximum cargo hold volume as an optimization target. Through optimization design of an oil tank of a 26500 DWT oil tanker, correctness and effectiveness of the method are proved, and it is evaluated that the optimization capability of the artificial bee colony optimization algorithm on the ship inner shell plate optimization design problem is higher than that of the other three algorithms.

Description

technical field [0001] The invention relates to the field of ship design, in particular to a method for optimal design of ship inner shell plates. Background technique [0002] Ship design is a cumbersome process. In order to find a suitable ship design plan, it is necessary to rely on experienced design experts to make repeated changes, calculations and checks based on the data of the mother ship, in order to find the most suitable ship design task document ( The scheme required by Ship Design Task Book, SDTB). With the development of optimization algorithms, many researchers apply optimization algorithms to ship design, which greatly improves the efficiency and quality of design. [0003] Because of the characteristics of strong carrying capacity and high economy of ships, 90% of the world's oil trade is transported by tankers. When oil tankers are sailing, due to the complex environment and harsh sailing conditions, various accidents occur frequently. These accidents c...

Problems solved by technology

In addition to the volume of the cargo hold, the speed of the ship is also an important criterion for measuring its carrying capacity. When optimizing the design, it is necessary to consider whether the speed of the ship under the rated power can meet the speed specified in the ship design task book after the ship's load capacity increases.
