Abstract: An analysis method of a damped plate structure, in which stiffeners are attached, a large structure, or a lamination sets a equivalent element through finite element modeling; defines a finite element governing equation including a strain component according to the bending of an MTIC method and interpolation which applies the equivalent element to a node cell; defines a complex freedom degree governing equation by applying the QZ decomposition method of LAPAC after converting a weight analysis function applied to the outside through the Hillbert conversion; determines one equivalent bending plate element by determining material loss coefficient applied as a direct attenuation performance from calculated time response after calculating the time response through a time inverse method and a modal coordinate system; and reduces the consumption of computer resources and human resources by simplifying a simulation for analyzing the same response by applying a complex number system.
