摘要:
提出了基于单元模态应变能变化的结构破损诊断方法,该方法仅以结构破损前后的模态振型和单元刚度矩阵为诊断信息. 实验研究表明,用有噪声影响的不完整测试模态振型数据时,此方法仍能得到较好的破损诊断结果,并且方法简便,便于实际应用.
Abstract:
A method based on elemental modal strain energy change is presented for detecting damage in a structure. This method only makes use of mode shapes before and after the occurrence of damage and elemental stiffness matrix as damage detection information. Experimental results illustrate that this method is robust to detect damage from the noisy and incomplete measured modes. 
