As explained in the flowchart presented in Fig. 1, the last but one step of the proposed methodology is applied determining the CWTs. The results of CWT application are presented in Figs. 15 to 18 for the Daubechies5 (Db5) and the Coiflet4 (Coif4) mother wavelets. Figure 12: First mode shape- f1=12.09Hz. Figure 13 : Second mode shape-f2=13.06Hz. Figure 14 : Fourth mode shape-f4=38.29Hz. (a) (b) Figure 15 : CWT using Db5-Case D1: (a) 3D view; (b) 2D view.
