AI Technical Summary

Technical Problem

The existing scale model design method has problems in processing feasibility, resulting in poor welding quality, affecting the test accuracy, and failing to effectively consider the impact of changes in reinforcement layout on the load-bearing capacity and buckling characteristics of the model.

Method used

By constructing a ship structure distortion scale model design method that takes into account the changes in reinforcement arrangement, the number and spacing of reinforcements can be flexibly adjusted to facilitate welding processing, and the cross-sectional dimensions of the longitudinal girder are adjusted through correction coefficients to maintain similarity, thereby ensuring processing quality and test accuracy.

Benefits of technology

The processing quality and experimental test accuracy of the scaled model are improved, while the similarity of the bearing capacity and buckling failure mode of the model before and after the change is maintained, enhancing the engineering application value.

Abstract

The present invention relates to a method for designing a scaled model of a ship structure distortion that takes into account changes in reinforcement arrangement, comprising the following steps: S1, designing and obtaining a scaled model P0 of a target ship structure stiffened plate; S2, dividing the target stiffened plate scaled model P0 into a plurality of stiffened plate units; S3, converting each stiffened plate unit in step S2 into a modified stiffened plate design unit with a smaller number of stiffeners and a larger stiffening spacing; S4, adjusting the cross-sectional dimensions of the longitudinal girder at the junction of adjacent stiffened plate units; S5, combining the stiffened plate scaled models designed in the above steps that take into account changes in reinforcement arrangement. The present invention can increase the model reinforcement spacing without affecting the bearing characteristics of the scaled model, improve the feasibility of the model processing technology, and thus improve the model processing quality and test accuracy; the method is based on the ship structure scaled similarity design theory, can directly obtain a scaled model that meets actual processing and test requirements, and has high engineering application value.
