摘要
基于TSP问题建立焊点路径数学模型。同时为改善遗传算法自身收敛速度慢问题,采取适应度计算评估、适应度比例选择步骤;为了提高计算速度与避免局部最优缺陷,采用自适应交叉、变异算子,以及加入进化逆转步骤操作来提升算法全局计算和搜索能力。最后利用RobotStuidio仿真软件建立点焊工艺加工站,进一步检验算法在实际编程中的应用。
The mathematical model of solder joint path is established based on TSP problem.In order to improve the slow convergence speed of the genetic algorithm itself,the steps of fitness calculation evaluation and fitness proportion selection are adopted;in order to avoid the defects of local optimum,adaptive crossover,mutation operator and evolutionary reverse operation are adopted to enhance the global search ability of the algorithm.Finally,the spot-welding process processing station is established by using RobotStuidio simulation software to further verify the application of the algorithm in practical programming.
