随着结构动力学求解问题的复杂化,有限元分析方法越来越起着关键作用。由于许多结构系统本身存在不确定性因素,试验数据存在随机误差,而计算的三类误差也会包含着不确定性误差,如何用有限的试验来修正和检验计算模型,最后得到具有一定置信度的有限元模型,即模型确认,在工程领域越来越得到关注。在与模型修正比较的基础上,详细讨论了模型确认的主要研究内容,并结合两个应用实例,讨论模型确认的总体思路与实现方法。 With the complexity of solving the structural dynamics problem, the finite element analysis method is playing a more and more important role. Due to the uncertainty of many structural systems, there are random errors in the experimental data, and the three types of errors in the calculation also contain uncertain errors. How to correct and test the calculation model with limited tests, and finally obtain a certain degree of confidence The finite element model, namely the model confirmation, is getting more and more attention in the field of engineering. Based on the comparison with the model modification, the main research contents of the model validation are discussed in detail, and the overall application of the two examples is discussed to discuss the general idea of ​​the model validation and its implementation.
