Calculation of Rayleigh Damping Coefficient using Shock Test Results
Abstract
To improve analysis efficiency in analyzing large structures, we divided certain equipment into sub-assemblies and analyzed them. Problems arose during the time-domain shock analysis of the transmitted shock load. To address this problem, we considered the application of a damping coefficient, and thus studied methods for estimating appropriate damping coefficients. We simulated shock loads on the target device, performed shock tests, and acquired data. We calculated modal parameters of the shock signal using the complex exponential method. Based on these results, we derived the Rayleigh damping coefficients.
