In this paper,an efficient,convenient and explicit method based on the Haar wavelet discretization ap-proach for analyzing the free vibration of the coupled laminated composite elliptical-cylindrical-elliptical shells(ECESs)with elastic boundary conditions is *** elliptical double curved shells are cou-pled on both end of cylindrical *** on the first-order shear deformation theory the equations of motion for ECES are derived by means of Hamilton’s *** separation of variables is first per-formed;*** components and rotations of any point of the ECES are expanded to the Haar wavelet series in the meridian direction and Fourier series in circumferential *** constants appearing from the integrating process are determined by boundary conditions,and thus the partial dif-ferential equations are transformed into algebraic *** solving the characteristic equation,the natural frequencies and mode shapes of coupled laminated composite ECES are *** present re-sults have been compared with those of the published *** comparison results show that this method has high accuracy,high reliability and also a higher convergence rate in attaining the frequencies of the coupled laminated composite ***,the effects of the main parameters such as material properties,geometrical parameters,and various boundary conditions,on the vibrational behavior of the coupled ECESs,are ***,new free vibration analysis results of the coupled laminated com-posited ECES,which can be used as benchmark data for researchers in this field,are reported through the parameter study.
