运用自适应遗传算法对二维声子晶体的带隙宽度进行优化设计,并与平面波展开法相结合,研究了由正方形排列的铅-环氧树脂构成的声子晶体的带隙宽度优化问题,发现自适应遗传算法可以有效地搜索到具有较宽完全声子带隙的优化单胞形式.
The bandgap width of two-dimensional phononic crystals is optimized by using adaptive genetic algorithm, and the combination of plane wave expansion method is used to study the bandgap width optimization of phononic crystals composed of square-shaped lead-epoxy resin. The adaptive genetic algorithm can effectively search for an optimized unit cell form with a wider complete phonon band gap.
