For Digital Assembly Assembly Sequence Planning Of Technical Studies

In recent years, under the prompting of the manufacturing technology and information technology, research on assembly design and planning has made a remarkable progress. This paper mainly studies the key technologies of digital assembly process planning: foundation of assembly model and its solution. In this thesis the mixed model structure is adopted to establish assembly model and the method is applied which is based on the initiative assembly sequence on assembly model solution. Concrete work is as follows:Firstly, the paper analyzes the function demands of assembly sequence planning system of facing digital assembly in detail, designs the function model of the system, and builds up the total structure of the system.Secondly, the paper explains the mixture structure and expatiates the principles of subassembly's classification, and designs a programming solution for assembly sequence planning module, a rule-based assembly planning method is introduced to set up the program structure which utilizes the assembly information model as input model and can finish assembly process planning by assembly structure analyzing, and introduced its contents in detail. This module integrated knowledge and experience of the process technician successfully to assembly sequence planning.Finally, basing on above research, the paper elaborates the whole course of developing the assembly sequence planning module, and takes the key component of tank engine as the example, confirms its feasibility.
