Assembly Error Space Dimensional Chain Construction and Assembly Process Optimization Method for Segmented Wing Structure
摘要
Aimed at the bottleneck problem that the accumulated transmission results of assembly errors cannot be predicted in advance, and a method was proposed for coordination error transmission accumulated calculation and coordinate dimension chain construction. Through analysis of assembly error coupling relationship and nonlinear transmission path model, construction method of assembly feature geometric error model based on key measurement points, multidirectional hybrid expression method for coordinated dimensional chain of multi separation surface wing assembly, modeling technology for error transmission and accumulation in multi process assembly of complex products, accurate construction of assembly coordination dimension chain and quantitative analysis of accumulated assembly error transmission results could be achieved, which could provide data foundation for construction of assembly error spatial dimension chain and optimization design of assembly process for segmented wing structure.
