摘要
结构损伤检测已成为工程领域中的前沿性课题之一.由于联合静动法模型修正技术包含了结构的众多信息,因此利用联合静动法模型修正技术进行结构损伤检测时能够得到较好的结果.在传统的联合静动法基础上,提出了一种基于有限元模型修正技术的新式联合静动法.结合一个简支梁的算例,讨论研究了该方法实现过程.仿真计算结果表明了该新式联合静动法模型修正技术的有效性.
The research of the structural damage detection is one of the foreland problems of the engineering area. As the combination of dynamic and static characters includes numerous information of a certain structure, good results of structural damage detection could be obtained by model updating based on combination of dynamic and static characters. An advanced combination of dynamic and static charac ters is put forward based on the traditional method. Using an example of a simply supported beam, it is shown that the model updating based on the advanced combination of dynamic and static characters for structural damage detection is better than the traditional method.
