Vibration Analysis of Circular and Annular Disc - A Review

Discs with different diametral holes and slots are widely used in the construction of automobiles, flywheels, clutch plates, saw cutters, missiles, vehicles and ship structures. The knowledge of natural frequencies of components is of great interest in the study of response of structures to various excitations. Hence one of application of rotor disc is tile cutter with central hole, fixed at inner edge and free at outer edge is topic of interest and its dynamic response is investigated by many researchers. This research paper presents a brief review of literature on methodologies used for analysing the vibration characteristics such as natural frequency and mode shapes of circular discs. Till now, much of the research work has been conducted on the vibration analysis of these types of structures based on analytical, numerical and experimental methods. In this paper, efforts have been made to review this type of literature. Finally summary of review and gaps found for future research have been discussed.
