Round sky and square earth hull structure lofting method and device and computer readable storage medium

Abstract

The invention discloses a round sky and square earth hull structure lofting method and device and a computer readable storage medium. The method comprises the steps that hull structure parameters areacquired, including the length of a bottom rectangle of a hull structure, the width of the bottom rectangle, the radius of a top circle, the distance from the projection of the circle center on the bottom of the hull structure to each long side of the bottom rectangle, the distance from the projection of the circle center on the bottom to each short side of the bottom rectangle and the height of the hull structure; according to the hull structure parameters, a three-dimensional graph of the hull structure is generated; a three-dimensional coordinate system is established with the length of thebottom rectangle being an X-axis, the width of the bottom rectangle being a Y-axis and the height of the hull structure being a Z-axis; lofting data corresponding to the three-dimensional graph in anXY plane coordinate system of the three-dimensional coordinate system is calculated; and according to the lofting data, a plane developed view of the hull structure is generated. Through the method,automatic lofting of the round sky and square earth hull structure can be realized, the lofting precision and efficiency of the round sky and square earth hull structure are improved, a lofting erroris lowered, and lofting duration is greatly shortened.

Description

technical field [0001] The present invention relates to the technical field of stakeout of a ship hull structure in a sky-round place, in particular to a method, a device and a computer-readable storage medium for setting out a ship hull structure in a sky-round place. Background technique [0002] In modern shipbuilding, due to the needs of the production process, the cylinder is connected to the square cylinder, so the connecting part of the cylinder and the square cylinder is often called the sky-round local structure. With the extensive application of sky-round local structures in hull structures, production designers are required to complete a large amount of structural lofting work. At present, the major shipyards mainly use the method of manual stakeout to draw the expansion diagram of the structure of the sky circle and the local area. Since this method needs to consume a lot of time for manual drawing to obtain the stakeout data, the drawing work of the expansion di...

Problems solved by technology

At present, the major shipyards mainly use the method of manual stakeout to draw the expansion diagram of the structure of the sky circle and the local area. Since this method needs to consume a lot of time for manual drawing to obtain the stakeout data, the drawing work of the expansion diagram can be completed, so the efficiency of stakeout is very low, and stakeout The error is large and the accuracy is low, and it is often necessary to add enough margin to ensure that the lofting accuracy meets the actual production needs, resulting in a large amount of material waste
