The numerical analysis for the four different temperatures was performed. The experimental modal analysis at the temperature 20°C for the control of natural frequencies and the mode shapes obtained from the numerical analysis at the temperature 20°C, was performed. The numerical modal analysis agrees well with experimental modal analysis and it can be used for prediction the natural frequencies and the mode shapes.
