模态参数的灵敏度分析在结构工程领域中的应用

The application of modes parameter sensitivity analysis in structural engineering

以模态参数灵敏度在结构优化、模型修正和损伤识别等领域中的应用为基础,介绍了它们的常用算法,并建立联结这3个应用领域的统一而简便的数学模型,揭示了数学模型间的内在联系,分析了模态参数灵敏度分析在上述领域应用时所处的技术位置及目前所能达到的应用水平。

Focusing on the application of modes parameter sensitivities in some practical construction fields such as structural optimization,modal updating and damage identification,the authors introduce the usual algorithms,and establish a unique but simple mathematic model with the combination of these three applied fields.In this paper,we reveal the interrelationship between mathematic models,and analyze the technique location and the current applying level when modes parameter sensitivity analysis is used in the above fields.
