Abstract (EN)
In this study, 85 cm offset printed antenna was used as a parabolic shell structure. The vibration on the antenna is measured with experimantal modal analysis. Frequency dependent graphs were obtained from measurement of vibration. These graphs are called (FRF) response frequency function. Resonans frequencies, and damping ratio were obtained from graphs.Two different studies were done. First one is Experimental Modal Analysis Method, Second one is Finite element vibration analysis method. These two method are compared with each other. Each other to validate the results was found.The resonance frequencies, mode shapes and damping ratios that are crucial in determining Dynamic properties of structures were calculated.
