AI Technical Summary
Traditional methods are insufficient to accurately characterize the multi-scale features and anisotropic distribution of the micro-roughness of high-precision gear teeth, which affects the accuracy of gear contact analysis and lubrication modeling.
Based on fractal theory, a three-dimensional point cloud benchmark model is constructed by discretizing the parametric equations of the gear tooth surface. Combined with fractal theory, a roughness field model that conforms to statistical characteristic constraints is generated, realizing the synergistic coupling of micro-undulation features and macro-geometry of the tooth surface.
It improves the accuracy and stability of rough tooth surface modeling, provides a reliable geometric basis for gear pair contact analysis, lubrication performance prediction and dynamic modeling, and promotes the development of related engineering technologies.
