摘要/Abstract

摘要： 紧凑拉伸试样参比电位差接线点布局多凭经验，本文提出了一种基于遗传算法对紧促拉伸试样参比电位差接线点寻优的方法.采用有限元法对拉伸试样的电位场分析，构建遗传算法的参比电位差模型，寻求最佳参比电位差值，得到紧凑拉伸试样最佳接线点位置.结果表明，两个参比电位差接线点之间的距离对参比电位差影响较大，靠近电流输入端与拉伸试样右上端内侧区域为最佳接线点位置.

Abstract: The layout of the wiring points of the reference potential difference of the compact tension specimen is mostly based on experience, in this paper, a genetic algorithm is proposed to optimize the tension specimen reference potential wiring points layout. The finite element method is used to analyze the potential field of the tensile specimen, the reference potential difference model of the genetic algorithm is constructed, the best reference potential difference value is found, and the optimal wiring point position of the compact tensile specimen is obtained. The results show that the distance between the reference potential difference wiring points has great influence on the reference potential difference, it is close to the current input and the inner part of the upper right end of the tensile specimen are the optimal wiring points position.

Key words: compact tensile specimen, genetic algorithm, reference potential difference, optimum wiring point, finite element method, crack monitoring
