Abstract

Modal analysis is used to determine the inherent dynamic characteristics of a system in forms of natural frequencies, damping factors and mode shapes. These parameters are important in the design of a system for dynamic loading conditions. Conventionally, modal analysis is performed with specific commercial tools. In this research paper the modal analysis of involute helical gear pair is carried out using finite element analysis tool ANSYS16.0. Gear noise and vibration is a major problem in many power transmission applications this problem becomes more significant in applications with higher operating speeds, where there is vibratory excitation which is related to the gear transmission error. The goal of modal analysis in this research paper is to determine the natural mode shapes and frequencies of the present helical gear pair and to comparatively analyse with frequencies of the geometrically modified asymmetric helical gear pair during free vibration as well as in pre-stress condition.
