摘要:
为提高变电站电力构架损伤检测效率和识别水平,更准确地把握电力构架结构整体的损伤程度,以现代大型变电站中常用的钢结构电力构架为研究对象,采用单元模态应变能变化率方法,对具有不同损伤部位和不同损伤程度的电力构架进行了损伤识别分析,结果表明:单元模态应变能变化率是受损钢结构电力构架的一个比较敏感的损伤标示量指标,采用该指标能够很好地对存在单一位置损伤或多位置损伤状态的电力构架进行损伤识别和定位.
Abstract:
In this paper，a study on the damage identification analysis of steel gantry structures in large-scalesubstations is put out.The damage diagnosis of steel gantry structures with different damage degree and dffer-ent damage sites are discussed based on the method of element modal strain energy change rate. The resultsshow that，modal strain energy change rate is a sensitive indicator index and it can be used to identify thedamages for the steel substation gantry structure simply and effectively.
