Abstract
The dynamic contact analysis of spiral bevel gear tooth surface is the basis of tooth surface design. In order to avoid the time-consuming process of finite element method(FEM) and the neglect of global tooth surface vibration by analytical method, a new dynamic fast loaded tooth surface contact analysis (DF-LTCA) method is proposed in this study. Firstly, the boundary element and internal node model of spiral bevel gear with adaptive boundary conditions are established to ensure the reusability of each node and unit. Second, elastodynamic partial differential equations for gear tooth surfaces with damped and body forces are formulated as equivalent vibration differential equations using the analog equation method (AEM) within the BEM framework, and solved via AEM’s direct integration method (DAEM) to obtain vibration displacements. Subsequently, a dynamic tooth surface contact model and solution method are established by coupling tooth surface vibration results with static clearance, formed the DF-LTCA method for spiral bevel gears. Finally, numerical examples and experiments are provided to verify the correctness of DF-LTCA.
