Abstract
Electrodynamic vibration exciter is used for measuring dynamic properties of components. On base of the results of measurement can be determined modal properties for example natural frequency, stiffness and damping factor. By obtaining these data computational model can be verified, respectively these data provide the necessary computing constants for further calculations and structural modifications. By measuring with the additional electrodynamic vibration exciter can also determine the frequency response function. This forms the basis for vibration and acoustic analysis of individual components, or structural assemblies and their possible modifications to eliminate the undesirable effects of vibration and noise. Vibration exciter is designed to be made life tests cyclically loaded components, or structural assemblies.
