摘要
为了达到调频质量阻尼系统最佳减振效果 ,需要对系统的参数进行优化 ,即求出最优频率比和最优阻尼比 .通过引进遗传算法 ,针对目标函数采用惩罚函数和适值标定有效引导遗传搜索 ,从而达到最优解 .计算结果表明了该算法对求解复杂优化问题的优越性 .
In order to achieve the most effective results of TMD system applied in diminishing the vibrations, there exists an optimization problem such as the optimum frequency ratio and optimum damp ratio. By using Genetic Algorithm, according to objective function the earliness and tardiness penalties and the mapping of adaptive values are employed to guide genetic search for reliability design, thus the optimized solutions are obtained. Results in this paper also proved that the algorithm is very convenient to optimize complicated problems.
