MATLAB Source Code for Spiral Bevel Gear Contact Analysis

I am pleased to share MATLAB source code specifically designed for spiral bevel gear contact analysis. This implementation features advanced contact mechanics algorithms that enable engineers and researchers to accurately study gear meshing behavior and contact patterns. The code incorporates mathematical models for tooth surface geometry calculation, load distribution analysis, and contact stress evaluation using Hertzian contact theory. Key functional modules include gear parameter initialization, tooth surface generation algorithms, contact path tracing routines, and stress calculation functions. The implementation utilizes MATLAB's computational capabilities for matrix operations and numerical integration to solve complex gear contact equations efficiently. This resource serves as both a practical engineering tool for gear design optimization and an educational reference for understanding MATLAB programming techniques in mechanical engineering applications. The code demonstrates proper handling of coordinate transformations, iterative calculation methods, and result visualization through contour plots and contact ellipse diagrams. I welcome feedback and suggestions for improvements to enhance the code's functionality and accuracy for various spiral bevel gear configurations and operating conditions.
