Method for calculating ship weight longitudinally distributed load density

Abstract

The invention discloses a method for calculating a ship weight longitudinally distributed load density. By adopting the method, the situation that partial weight losses or distortion of equipment at aship bow / stern can be avoided, so that weight distributed load density is more reasonable and accurate. According to the method for calculating the ship weight longitudinally distributed load density, the ship bow and the stern can serve as complete standard theoretical station distances correspondingly, 20 standard theoretical station distances in a traditional method are expanded to be 22 standard theoretical station distances, and then weight of each equipment or goods on a ship is equivalently distributed on the standard theoretical station distances in theoretical station distance ranges where the equipment or the goods are located according to a static force equivalence principle; and the weight distributed in the ship bow standard theoretical station distance and the stern standard theoretical station distance is converted into two standard theoretical station distances adjacent to the ship bow standard theoretical station distance and the stern standard theoretical station distance, and finally weight distribution of the 20 standard theoretical station distances of a hull, namely, the ship weight longitudinally distributed load density, is obtained. Partial weight lossesor distortion of the equipment at the ship bow / stern is avoided, and weight distributed load density is more accurate.

Description

technical field [0001] The invention relates to the technical field of ship weight calculation, in particular to a method for calculating the longitudinal distribution load strength of ship weight. Background technique [0002] The weight curve is a curve that describes the distribution of the ship's weight along the length of the ship. Its ordinate indicates the weight distribution load intensity acting on the unit length, which is an important design index for the ship's anti-trim design. The method of drawing the weight curve is to distribute the weight of various equipment or items of the ship within the corresponding range of ship length. Firstly, the whole ship is divided into 20 theoretical station distances along the length of the ship, and the weights are distributed within the corresponding theoretical station distances according to the static equivalent principle, and then superimposed one by one to obtain the longitudinal weight distribution in each station dista...

AI Technical Summary

Problems solved by technology

The traditional processing method for the protruding part of the weight of equipment or objects will lead to the absence of part of the weight or the distortion of the equivalent segmented weight to a certain extent, which cannot meet the high-precision design requirements

In addition, during the design process, the number or location of ship equipment often changes, resulting in changes in the original ship weight longitudinal distribution load strength and center of gravity, which cannot meet the requirements for use after the change, and it is necessary to recalculate the distributed load strength. consume a lot of manpower and material resources
