Non-circular Gear Modal Analysis Based on ABAQUS

In this paper, the design of non-circular section of the curve profile of gear method in Pro / E drawing a non-circular gear teeth, and draw out the mirror and drawing commands through a three-dimensional model of the first-order and third-order elliptical gears. And oval gear created virtual assembly, a complete model of oval gear deputy. According to the theory of elasticity and modal finite element analysis software ABAQUS, non-circular gear designed to create a finite element analysis model of vice, so that various modal analysis oval gear, get the oval gear each mode of mode shapes and natural frequencies, the analysis is verified by comparing the dynamic characteristics of the oval gear (non-circular gears).
