摘 要: 为了考察新型钢铅组合耗能器(NCSLD)的力学性能和提高其耗能能力,利用电液伺服压剪试验机对NCSLD耗能器进行力学性能试验,采用ANSYS实体建模的方法对耗能器进行大量的数值分析,并对性能试验和数值分析的结果进行对比,研究耗能器的滞回特征参数与其6个几何参数之间的关系,回归出二者之间的公式.提出评价耗能器性能优劣的标准及其附加条件,并以此标准为依据,利用均匀设计法和遗传算法分别对耗能器的6个几何参数进行优选.结果表明遗传算法的选优效果要好于均匀设计法,同时得到一系列性能良好的NCSLD耗能器. In order to study mechanical properties of a new-style combined steel lead damper(NCSLD) and improve its energy dissipation capacity,an electro-hydraulic servo press-shear machine was employed to conduct the performance tests of NCSLD.ANSYS entity modeling method was used for massive numerical analyses of NCSLD.Comparison between performance tests and numerical analyses was carried out.Relationship between hysteretic characteristic parameters of NCSLD and its six geometric parameters was studied,and the for...
