Embodiment Construction

[0036] The present invention will be described in detail below in conjunction with the drawings.

[0037] A method for identifying sub-assemblies in assembly sequence planning includes the following steps:

[0038] The first step is to establish a weighted undirected connection diagram according to the relationship between the assemblies, confirm the basic parts, and the weighted undirected connection diagram relationship model such as figure 1 Shown

[0039] The assembly is composed of n parts, set Is a collection of assembly parts. According to the connection relationship of the parts, the weighted undirected connection diagram G of the assembly is established,

[0040]

[0041] among them, Represents a collection of components in an assembly;

[0042] Indicates that there is a tight connection or a contact connection between the parts;

[0043] , The weight wij represented by the seven-tuple is used to identify whether eij is a fastened connecting edge or a contact connecting...

Abstract

The invention discloses a recognition method for a subassembly in assembly sequence planning. The recognition method comprises the steps of building a weighted non-vector connection diagram through a relationship between assemblies, and then determining basic parts; judging the subassembly according to the definition and the association degree of parts; finally, realizing a subassembly recognition algorithm through designing and compiling under a Matlab (matrix laboratory) environment. According to the recognition method disclosed by the invention, an algorithm instance verifies that a great significance in realizing assembly sequence optimization and shortening assembly sequence planning time is obtained by applying the subassembly recognition to the assembly sequence planning, an assembly sequence is simplified, and the assembly difficulty and the assembly cost are reduced.

Description

Technical field [0001] The invention relates to the field of assembly sequence planning, in particular to a method for identifying sub-assemblies in assembly sequence planning. Background technique [0002] In the assembly of different scales in various environments, it may face problems such as combinatorial explosion, excessive search space and constrained combinatorial exponential growth. In the intelligent sequence planning, facing products with large number of components, complex structure, high assembly requirements and difficult component identification, the division of sub-assemblies can make the assembly structure of different scales hierarchical and solve the problem of assembly sequence planning. The decomposition into several sub-problems reduces the difficulty of assembly, facilitates the generation process of assembly sequences, and improves planning efficiency. That can better guide product assembly and reduce assembly costs. [0003] Regarding the recognition of s...
