| Abstract: | There are many 3-D parts with complicated profile in process of Body in White assembly,which cause assembly fitting problems.In order to solve this kind of problems,a novel algorithm based on genetic algorithm to research the global optimal fitting position of two space curves is discussed in the paper,and the optimal functions are presented respectively.The solution to constrained optimization problem by applying genetic algorithm is described in detail,and the whole diagnosis flow of GA is presented.Some improved GA methods used in the constrained optimization is discussed. |
