摘要
针对工程结构的健康监测,提出一种基于柔度矩阵法的损伤识别方法,只需结构的低阶模态参数便可识别结构的损伤位置和程度,克服了实际应用中高阶模态参数较难获得的缺陷,并通过一个悬臂结构损伤识别的数值模拟验证了该方法的有效性.
Damage health monitoring. identification based on flexibility matrix method is suggested for engineering structures This method only requires low order modal parameters of structure to locate identifies the degree practical application damage and of damage to overcome high order modal parameters being more difficult to obtain in The efficiency of the method is validated by numerical simulation of a damage cantilever beam.
