摘要
采用模态应变能变化率方法进行结构损伤识别、定位,并提出了一种只需低阶模态即可精确求解损伤程度的方法.通过算例表明,该方法不仅能够精确的估计损伤程度,而且具有良好的抗噪性,并能够智能修正损伤定位所产生的误判,方法简单,具有很强的实用性.
A precise solution method is proposed in this paper,which can estimate damage degree with lower modes after identifying and locating damage with mode strain energy changing method.The results show that the method can not only estimate precisely damage degree but resist noise and it also can revise the wrong identification localization for damage.The method is simple and practical,which can be applied in engineering domain.
