Embodiment Construction

[0010] A convenient method for controlling deformation of hull segmented construction, the steps of the method are as follows:

[0011] 1. Design model file identification and design model file import operation: analyze the output file code of the steel structure 3D modeling software, be familiar with the file code, compile the recognition program, and be able to identify the file type output by the modeling software;

[0012] 2. Acquisition of physical shape data: adopt three-dimensional measurement technology to collect data of physical shape feature points to form a data file of physical shape feature points;

[0013] 3. Acquisition data import operation: identify the acquisition data files through the identification software, establish a software interface, import the acquisition data files into the graphics operation software, connect the feature point data into the physical space shape, and convert the three-dimensional coordinates to the design model at the same time pa...

Abstract

The invention relates to the technical field of ship and ocean engineering equipment, in particular to a portable ship block deformation control method. The method comprises the following steps of 1, identifying a design model document and importing the design model document; 2, sampling physical profile data; 3, importing the sampled data; and 4, comparing and analyzing the design model and the sampled model. According to the method provided by the invention, no margin ship building can be realized, the ship building efficiency can be speeded up, and technical support for batch ship building precision control management is provided, and promotion and inheritance can be reached. Moreover, the defects that the existing ship building experience and margin distribution method need long time to accumulate, are obviously lagged compared with the current large ship building technique development trend and do not have promotion and inheritance are overcome.

Description

Technical field: [0001] The invention relates to the technical field of ships and ocean engineering equipment, in particular to a convenient method for controlling the deformation of a hull in segmental construction. Background technique: [0002] The segmented construction of the hull, especially the segmented construction of the parallel mid-hull of a large ship, or the large number of structurally similar segments during the construction of a series of ships, the shipyard often uses the existing construction experience to make redundant Quantity distribution, and finally meet the accuracy requirements. At present, most of the construction experience and margin allocation methods are mastered by experienced craftsmen in shipyards, and the accumulation of such experience takes a long time, lagging behind the development trend of contemporary large-scale shipbuilding technology, and does not have the ability to promote and transfer sex. Invention content: [0003] The te...
