TL;DR: In this paper, the authors discuss ODS measurements and their relationship to experimental modal parameters, and discuss the relationship between ODS measurement and experimental modality parameters, including mode shapes and operating deflection shapes.
Abstract: Mode shapes and operating deflection shapes (ODS’s) are related to one another. In fact, ODS’s are always measured in order to obtain mode shapes. Yet, they are quite different from one another in a number of ways. In this paper, we will discuss ODS measurements, and their relationship to experimental modal parameters.
