Abstract:In studying dynamic behavior of mechanical systems very often a three-step approach is used. In this classic approach, Step 1 involves analyzing actual running characteristics of a machine, structure, or process. Step 2 involves the determination of frequency response functions between various locations on the test system. Step 3 may then involve extraction of specific characteristics of the system such as structural mode shapes, damping parameters, stiffness values, or system resonant frequencies. Often it is… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
