提出一种改进的灵敏度方法用于工程结构损伤检测中.通过在迭代算法中引入一个“加速”公式来迅速获得足够精确的识别结果,避免了多次迭代,可以大大减少计算花费.用文献[8]和文献[10]中的两个数值算例对所提方法进行了验证,并把结果和原文中的计算结果进行比较.结果表明:采用改进的方法一般只需经过一次计算即可获得精度更高的识别结果,避免了多次迭代,显著减少了计算花费,显示了改进方法突出的优越性.
An improved sensitivity method is proposed for damage detection in engineering structures.It can quickly and accurately obtain the recognition results by introducing an “acceleration ” formula into the iterative algorithm, avoiding many iterations and greatly reducing the computational cost. The proposed method is verified by two numerical examples in [8] and [10], and the results are compared with the results in the original text.The results show that using the improved method generally requires only one calculation The recognition result with higher accuracy can be obtained, multiple iterations are avoided, the computational cost is significantly reduced, and the superiority of the improved method is prominently shown.
