摘要
本文综述了工程上常用的三种反分析方法：直接法、逆解法和对偶边界法，介绍了每种方法的原理和计算步骤．计算结果显示，对偶边界法具有较高的分析精度．在待识别参数较少的情况下，三种方法给出了同样的结果．但在待识别参数较多的情况下，直接法和逆解法精度较差，在某些情况下甚至不收敛．
This paper summarizes three commonly used back analysis methods in engineering, i. e. direct formulation. inverse formulation and dual boundary control formulation. The principles and computational steps for each method are givenherein. The computation shows the dual boundary control formulation resultsin high accuracy. In the case of identifying fewer parameters, the three methods give the same results. However in the case of identifying more parameters,clirect and inverse formulations perform worse and eved diverge.
