Abstract
In the present paper, Natural frequencies of gas turbine disc determined by Holzer’s method as well as Fast Fourier Transform spectrum analyzer are compared. Hub is a circular disc made up of Aluminium alloy to whose outer periphery blades are welded. Disk’s inner end is coupled with a shaft. Thus the Natural frequencies of this component can be kept at a minimum range. Also this material exhibits good properties such as low embrittlement, low toxicity, easy formation of complex shapes and some other economical issues. Many gas turbine models have adopted mild steel hub. Reduction of torsional vibrations in the circular disc results in decreased Natural frequency of gas turbine assembly. This paper also discuss the information to find stiffness, damping ratio and amplitude.
