    本文对结构损伤的参数识别问题利用增量法对质量阵和刚度阵进行修正,同时还采用了小参数摄动法对结构模态进行参数识别,并利用缩聚法对有限元模型进行降阶,从而有效地进行结构损伤的识别.

    In this paper, the problem of parameter indentification on structual damage was used, the increment meth-od was made use of mass matrix and stiffness matrix to correct, in the menntime the decimal parameter perturbation method was used in the structual mode parameter indentification. the condensed method used FEM mode to demote, thus the effective damage indentification was carried out in the structure.
