摘要
结构灵敏度分析在工程领域具有广泛的意义。针对现有结构灵敏度分析方法中存在的问题，借鉴于模态综合技术在计算上的简便性，提出并建立了结构灵敏度分析的子结构方法（ＳＳＳＡ法）。在理论分析的基础上，编制了有限元程序，并对固支梁进行了验算。提出的方法适用于一般结构系统，对大型复杂结构当更为有效。
The problem structrual sensitivity analysis is of wide significance in the field of engineering. In this paper, the substructure method (SSSA),which uses the technique of modal synthesis to simplify the calculation, is aimed at the improvement on the weakness in the existing methods. Based on the theoretical analysis, the finite element analysis program is developed and examined through the analysis of a fixed beam. The method presented in this paper is applicable for the general structural system and would be a very effective method for the analysis of large and complex structures.
