Description

technical field [0001] The invention mainly relates to the field of batch selection assembly and manufacturing of various parts, in particular to the problem of multi-dimensional dimension chain optimization of parts and the problem of selecting assembly pairing, product tolerance analysis and tolerance synthesis, and in particular to a multi-dimensional hybrid particle swarm algorithm-based multi-dimensional Orientation selects the assembly optimization method. Background technique [0002] Assembly is one of the important links in the product manufacturing process. In the mass assembly process, the assembly success rate and assembly function requirements are important indicators of product assembly assurance. The assembly success rate and assembly function requirements of the product are affected by the comprehensive effect of the size and shape and position accuracy of the matching features of the parts; when the size and shape and position accuracy of the matching featu...

Problems solved by technology

[0003]1) When the design size and shape accuracy of the part are too high, and the processing and manufacturing capacity of the part cannot meet the design requirements, resulting in the part size and shape accuracy cannot be guaranteed, The assembly success rate and assembly function requirements of the product cannot meet the design requirements

[0004]2) Although the processing accuracy of the part meets the design level requirements of the part size and shape and position accuracy, the batch size or shape and position error does not meet the normal due to the large processing error When designing statistical laws such as distribution, there may also be problems with the assembly success rate and assembly function requirements of the product
