Material Characterization Of Gyroscope Isolator Using Modal Test Data
Published 2014 · Computer Science
Gyroscopes are widely used in stabilization of turret systems where high shocks are encountered. Use of isolation material with them is essential to obtain reliable rotation data considering the intensity of shocks. Usually, each gyroscope comes with an isolator panel specific to itself. In certain situations, however, a proper isolator configuration is unavailable for the gyroscope. In this study, analyses required to use a sandwich panel isolator with a gyroscope other than its original one are presented. Isolation material is modeled as orthotropic and its characteristic properties are obtained from the comparison between the modal tests and the finite element model by using optimization. Effects of full realization of the boundary conditions on the modal data are also shown.
