【Abstract】 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.更多还原
