摘要
提出适宜的适应度函数,将遗传算法的种群思想引入模拟退火算法中,构造出遗传算法与模拟退火算法的组合算法,用于空间结构振动抑制的阻尼器位置和数量寻优。通过空间网壳在不同冲击荷载作用下的算例分析发现,若设置合适的控制参数,运用组合算法可迅速准确地找到全局最优解方案。
An improved simulated annealing algorithm integreated with the idea from genetic algorithm as well as the adapting function is put forward as a mixed algorithm for optimization of damper quantity and placement in vibration reduction of spatial reticulated structures. A typical reticulated shell structure under different impact loadings is taken as an example to demonstrate the advantages and effectiveness of the mixed algorithm with proper parameters.
