Problems solved by technology

In the case where the same component object exists within a segment, the correct component object cannot be distinguished only by the encoding of the part
At present, there is no special assembly analysis method for hull parts on the market, and traditional mechanical assembly methods cannot be applied to the assembly analysis of hull parts

Embodiment Construction

[0100] In order to make it easier for those skilled in the art to understand and implement the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. All the embodiments are operated according to the above-mentioned method, and each embodiment only records key technical data.

[0101] Such as Figure 6 As shown, there are multiple groups with the same name XF02 under the group in D5P-C, and only two of them are shown now. It can be seen from the figure that the distance between the center of gravity of the part "XF02-F1.1" and the part "XF02-W0.1" in the group is smaller than that of the part "XF02-W0.2" outside the group, and the distance between the center of gravity of the part "XF02-F1. 2" as well. The reason for this principle is that the parts in the group are welded together, and the distance between their centers of gravity must be close. Even if the center of gravity...

Abstract

The invention relates to an automatic assembly method for a three-dimensional ship modeling part, which judges the accurate component attribution of the part thereof and two components with the same component name and different installation positions by taking a part code and gravity center data as a basis and taking a principle that the average gravity center distance sum of parts in the component is smallest as a reference. The method has the advantages of simple principle, little data demand and fast analysis process, is proved by using of having the judgment accuracy rate of 100 percent, is an optimal analysis method for developing a ship body automatic assembly program, is suitable for assembly analysis of the ship body part, also has certain reference value to assembly analysis of other industries and specialties and is a new assembly analysis method.

Description

technical field [0001] The invention relates to an automatic assembly method, in particular to an automatic assembly method for three-dimensional ship modeling parts. It belongs to the field of ship three-dimensional design. Background technique [0002] Assembly in 3D system is a kind of virtual assembly. Virtual assembly refers to the use of virtual reality technology to pre-assemble the designed three-dimensional model of the product in a virtual environment, and to improve the design and assembly of the product through analysis, evaluation, planning, simulation, etc. structure to achieve product assemblability and economy. In the hull profession, virtual assembly involves two aspects: one is to determine the welding relationship between parts, and the other is to determine the attribution of parts. The assembly problem involved in this application belongs to the second aspect, and this kind of assembly is also called component assembly. The purpose of the virtual com...
