Problems solved by technology

In the traditional mechanical product assembly process, most enterprises use experienced assembly engineers to assemble with their own experience, but when there are too many assembly parts, the number of product assembly sequences and the number of product parts increase exponentially Therefore, for complex mechanical products with a large number of parts, there will be an assembly sequence combination explosion problem. It is difficult to determine the assembly sequence based on the experience of the assembly engineer. Even if it can be determined, it is difficult to ensure the rationality and superiority of the assembly sequence, resulting in Increased product manufacturing costs and extended development cycles have reduced product market competitiveness

Description

technical field [0001] The invention relates to the field of complex mechanical product assembly planning, in particular to a complex mechanical product assembly sequence planning method based on fireworks algorithm. Background technique [0002] Assembly planning includes three parts: assembly modeling, assembly sequence planning, and assembly path planning. Assembly sequence planning is the core of assembly planning, which is directly related to the assembly cost of products. In the traditional mechanical product assembly process, most enterprises use experienced assembly engineers to assemble with their own experience, but when there are too many assembly parts, the number of product assembly sequences and the number of product parts increase exponentially Therefore, for complex mechanical products with a large number of parts, there will be an assembly sequence combination explosion problem. It is difficult to determine the assembly sequence based on the experience of th...
