The main aim of our project is to study the effect of shape change and angular orientation of holes on Vibration characteristics such as natural frequency and mode shapes. In field of rotating components and structures the circular disc with different size and shapes of holes are used. We will study the change of these shapes of holes on the natural frequency. These holes usually cause change in some of the properties of the components load carrying capacity, decrease in weight of component and stresses developed in the component etc. The 3D model will be drawn with the help of CATIA software. The modal analysis will be carried out with the help of ANSYS software. The experimental testing will be carried out by using Impact Hammer Test & FFT Analyzer. The comparison will be carried out between the experimental and analysis results and then the result & conclusion will be drawn.
