The Study of Coupling Vibration and Dynamic Stress Simulation for WN Gear Pair

Based on double arc gear characteristics and considering system error, a multi-degree-freedom(Tangential-Radial-Axial) coupled vibration dynamics analysis model was established. In this article, we established the three-dimensional solid model by using PROE, imported the arc gear three-dimensional model into Ansys software through the data interface of Ansys software and PROE software and conducted a three-dimensional simulation anasys of the impact of dynamic contact. By applying load, it conducted a stress analysis for double arc gear and gain the double arc gear's the effective stress clouds. Meanwhile, the rigid-flexible body of gear dynamic contact model based on ANSYS / LS-DYNA was established and the dynamic simulation anasys for WN gear was analyzed. The results demonstrated that the tangential and axial vibration of double arc gear is significantly greater than the radial vibration.
