Missile's which cruise in air are susceptible to gust loading which leads to fatigue failure, if the missile operates at its own natural frequency. Geometrical model of the typical missile is developed and computational modal analysis is performed. The geometrical model is fabricated and Experimental Modal analysis is performed on it with Free-Free boundary conditions. The obtained natural frequencies are compared with the computational results and the mode shapes are identified.General Terms -Computational Modal analysis, experimental modal analysis i.e. impact hammer test.
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.
