摘要
根据PCB板结构的特点,利用自由度凝聚技术给出了元器件模型的自由度凝聚方法,并在此基础上利用子结构安装技术给出了PCB板支撑布局优化建模方法。该方法大大缩减了结构优化分析自由度的数量,并便于实现元器件组件计算结果的重用。提出了支撑点与PCB板节点不重合时的解决方法。利用遗传算法和ANSYS二次开发技术相结合,开发了支撑布局优化求解程序。优化算例结果表明该优化方法是有效的和可行的。
By using method of condensation of degree of freedom, a condensation method of degree of freedom for parts and components is proposed, and base on this method, a new support position layout optimization method in printed circuit board structure is built up. This optimization method makes computation amount reduce greatly and reuse the condensation model easily. Additionally, by using genetic algorithm method and seconddevelop technique, the solving software is developed. Optimization examples show the optimization method is feasible and effective for engineering projects.
