可传递性函数是仅输出函数，具有一个主要优点。当定义良好时，这些函数变得与作用力的谱内容无关。因此，基于这些类型的功能的操作模态分析（OMA）的方法将不会受到任何有色或谐波力激励的结构。这是与OMA领域中的现有技术相比的主要优点。基于传递率的操作模态分析（TOMA）是几年前首次引入的，本文将总结这一新研究领域背后的基础知识。其次，最近开发的p-TOMA将介绍和说明通过数值实验。
Transmissibility functions are output-only functions that have one major advantage. When well-defined these functions become independent from the spectral content of the acting forces. A method for Operational Modal Analysis (OMA) based upon these type of functions would therefore not be affected by any colored or harmonic forces exciting the structure. This is a major advantage compared to existing techniques in the field of OMA. Transmissibility based Operational Modal Analysis (TOMA) was first introduced a few years ago and this paper will summarize the basics behind this new field of study. Secondly the recently developed p-TOMA will be presented and illustrated by means of a numerical experiment.
