Abstract: Based on the Ritz theory, an analytical method of solving the natural characteristics of hard-coating cantilever laminate plate was developed. The strain and kinetic energy of composite plate was characterized by the displacement of neutral surface, then the free vibration equation was derived and the methods of solving natural frequency, mode shape and modal loss factor were presented. A T300/QY89l1 laminate plate coated with NiCoCrAlY+YSZ hard coating was chosen to demonstrate the as-proposed method. The natural characteristics were calculated by the as-proposed method and ANSYS software, respectively. The obtained results were compared with the purpose of assessing the rationality of the method proposed. The practice shows that the natural characteristic parameters of hard-coating cantilever laminate plate with engineering significance can be obtained by treating the hard-coating layer as a special layer and implementing the inverse transformation of dimension.
