Dayaram Chouhan, Akhilesh Lodwal

Abstract: Gearing is a very important term in automobiles, industrial, production and every place where power transmission requires. Gear is an important machine component in many mechanical power transmission system. It has a wide range of applications because of its high degree of reliability and compactness. Vibration induced by gear is a major problem in many power transmission system and has been widely studied, it is an important topic for further studies in engineering field. Natural frequencies and mode shapes are the important design parameters of a system. Mathematical modelling of system may be done to find the natural frequency & mode shape. In present work, the effect of design parameters on the natural frequencies are investigated.

Keywords: 3D modelling, modal analysis two stage gear-rotor assembly, natural frequency, mode shape
