摘　　要：经过几十年的发展,关于质量调谐阻尼器(TMD)性能的研究已日趋成熟,而只有少数文献从效-费比方面对TMD减震控制系统进行经济性的研究,这也是制约TMD减震控制技术发展的原因之一。研究了改进多种群遗传算法在考虑SSI效应的TMD控制结构中效-费比优化问题。首先,分析TMD装置系统的全寿命周期费用LCC(LifeCycleCost)的构成,建立TMD各组成部分非线性成本函数,然后,将成本函数代入改进多种群遗传算法,在满足所设置的结构减震百分率基础上寻求成本最小化,即在满足业主具体的抗震性能要求的前提下,以效-费比为优化性能指标,求出减振控制系统的最优参数,以最低的费用,达到最好的减震效果。With decades of development,the research on the performance of mass tuners(TMD)has become more and more mature,and only a few documents have conducted economic research on the TMD damping control system in terms of efficiency-cost ratio,which has always restricted TMD damping.One of the reasons for the development of control technology.This paper studies the efficiency-cost ratio optimization problem of the improved multi-population genetic algorithm in the TMD control structure considering the SSI effect.First,analyze the composition of the Life Cycle Cost(LCC)of the TMD device system,establish the non-linear cost function of each component of the TMD,and then substitute the cost function into the improved multi-group genetic algorithm to meet the requirements of the set structure shock absorption seek cost minimization on the basis of percentage,that is,on the premise of meeting the owner’s specific seismic performance requirements,use efficiency-cost ratio as the optimization performance index to find the optimal parameters of the vibration reduction control system,and achieve the best with the lowest cost The shock absorption effect,saving resources.
