Contact-impact analysis of hypoid gear with finite element method
摘要
Abstract
The contact - impact action of spiral bevel gear system was simulated based on the finite element analysis software. A pair of hypoid gear as an example, modeled by simulating machining process based on CATIA V5 controlled by Visual Basic and NURBS surface reconstruction, was developed. Subsequently, numerical a-nalysis of gears contact - impact was performed on ABAQUS. The results show that the contact pressure within the contact area is periodic variation, and the maximum transient contact force value can reach about twice the stable value in the impact process. In addition, the contact force and the bending stress appear sharp fluctuation when the first tooth gets into meshing. It can be used to provide reference for improving gears transmission performance.关键词
