摘　　要：提出了一种基于类柔度矩阵差值的结构损伤诊断方法。其是用结构损伤前和损伤后的类柔度矩阵差值作为诊断损伤的敏感因子。详细讨论了该诊断方法,并用仿真算例说明了这种方法的有效性和可行性,并用实验验证了这种方法的有效性和可行性。This paper put forward a structural damage detection method that is the diagnosis method of structure damage based on the differeance of analogous flexibility matrix.It takes the differeance of analogous flexibility matrix as the sensitive factor of diagnosing damages. This paper discusses in detail the method and explains its efficiency and feasibility by using simulation calculation example. Its efficiency and feasibility was verified by using experiment.
