Embodiment Construction

[0012] The present invention will be described in further detail below.

[0013] A method for assembly sequence planning, including (1) knowledge-based assembly sequence generation method, (2) assembly sequence generation method based on component recognition, (3) assembly sequence generation method based on priority constraint relationship, (4) cut-based assembly sequence generation method based on set method, (5) assembly sequence generation method based on disassembly method; it is characterized in that this method uses knowledge such as sequence priority constraints and assembly resource constraints, and the system takes the product CAD model as input and obtains it through human-computer interaction The assembly of parts is pre-constrained, and the minimum cut set of the characteristic graph of the product is solved by the graph search method to generate the assembly sequence, and the corresponding mechanical products and fixtures are designed; this method is more effectiv...

Abstract

The invention relates to an assembly sequence planning method. According to the method, a general assembly body model is disassembled to sub assembly components; the sub assembly components are assembled into a general assembly body model; an optimal assembly sequence can be obtained based on the connection of the general assembly body model; the sub assembly components are disassembled into sub assembly parts; the sub assembly parts are assembled into sub assembly components; a disassembly sequence can be obtained through the sub assembly parts; algorithm optimization and evaluation are carried out through the disassembly sequence; an optimal disassembly sequence is selected through the algorithm optimization and evaluation; and the sub assembly parts can be obtained through selecting the optimal disassembly sequence.

Description

technical field [0001] The invention relates to the technical field of planning methods, in particular to a method for assembly sequence planning. Background technique [0002] Facing the complexity and diversity of current aviation products, the current existing technologies still have the following deficiencies: [0003] (1) The fixture design management platform based on Teamcenter in the PDM environment must be optimized and upgraded to keep pace with the rapid development of aviation companies, so as to meet the needs of fixture design for aviation complex parts. (2) There are still some old drawings from the 1960s to 1980s in the two-dimensional drawings of aviation fixture design. These drawings have not been fully preserved or updated, and an electronic library needs to be established. In addition, the fixture standard parts library and fixture library are not perfect and need to be supplemented and updated . (3) The disassembly method is better for the availabilit...
