基于层间隔震体系两质点简化模型，建立了以基底剪力最小为优化目标的参数优化方法，采用 NS-GA-Ⅱ优化得到层间隔震体系在不同质量比下的最优频率比和最优阻尼比；建立了体系的能量和功率方程，从能量和功率角度分别分析了不同质量比下的层间隔震结构最优参数模型能量的传递、耗散和转化关系以及机理表现。

Based on simplified model of two mass-points of inter-story isolation system ,the parameter optimiza-tion method was established which made base shear minimum as optimization target .The optimal frequency ratio and the optimal damping ratio of inter-story isolation system under different mass ratios were obtained by using the Non-dominated Sorting Genetic Algorithm with Elitism (NSGA-Ⅱ) .The energy and power equa-tions of the system were also established ,and the energy transfer ,dissipation ,conversion relations and mech-anism performance of the optimal parameter model of inter-story isolation system under different mass ratios were analyzed respectively from the perspectives of energy and power .
