摘要
为优化埋入光纤刚挠结合光电印制板结构参数,减小内部光纤的应力和偏移量,将光纤应力和偏移分别作为目标函数,结合响应面法(RSM)和非支配排序遗传算法(NSGA-Ⅱ)对刚挠结合光电印制板结构参数进行双目标优化.建立了埋入光纤刚挠结合光电印制板的有限元分析模型,并对其施加热固耦合载荷;利用RSM得到了内部光纤的应力和偏移量的拟合模型与回归方程;基于光纤最大应力和最大偏移量这两个目标最小的原则,采用NSGA-Ⅱ对埋入光纤刚挠结合光电印制板结构进行优化设计,得到了优化后的Pareto解集,并验证了优化解集的准确性.
Abstract
To optimize the structural parameters of the buried fiber rigid-flexible optoelectronic PCB and reduce the stress and off-set of the internal fiber,the Response Surface Method(RSM)and the Non-dominated Sorting Genetic Algorithm(NSGA-Ⅱ)were combined to optimize the structural parameters of the rigid-flexible optoelectronic PCB as the objective functions respectively.The finite element analysis model of the buried fiber rigid-flexible optoelectronic PCB was established and the thermo solid cou-pling load was applied to it;the fitted model and regression equation of the stress and offset of the internal fiber were obtained by the RSM;based on the principle of minimizing the two objectives of maximum stress and maximum offset of the fiber,the NSGA-Ⅱ was used to optimize the structure of the buried fiber rigid-flexible optoelectronic PCB and obtain the optimized Pareto solution set was obtained,and the accuracy of the optimized solution set was verified.
