Cepstral methods of operational modal analysis to separate multiple sources

该项目旨在开发在多个复杂源（如旋转机械）情况下的运行模态分析新方法。该项目将获得缩放模式形状以及分离的缩放源。其中一个主要的应用将是提高机器的性能，通过分离的强制函数的缩放估计，使其更容易找到故障参数的趋势单调走向失败，从而大大提高剩余的有用设备寿命的估计。该应用程序的另一个好处是，如果源和模态模型都按比例缩放，则能够预测机器或物体的整体噪声辐射。

This project aims to develop new methods of operational modal analysis in situations with multiple complex sources, such as rotating machines. The project will obtain scaled mode shapes as well as separated scaled sources. One of the main applications will be to improve the prognostics of machines by having separated scaled estimates of the forcing functions to make it easier to find fault parameters which trend monotonically towards failure, and thus greatly improve the estimates of remaining useful equipment life. An additional benefit of the application will be the ability to predict overall noise radiation from a machine or object if both the sources and modal models are scaled.
