Current finite element (FE) models for gear analysis are computationally expensive. We will develop a software tool in Excel to efficiently assess the effect of different root geometries on gear tooth bending strength. The tool will assess the change in root stress as the root fillet shape is changed, using a 2-D model of a representative gear tooth using an A to B comparison. This is assumed to correlate to equivalent stress reduction in an actual gear. The tool will be validated by comparing the root stress found using the software to a FE analysis of root stress using ANSYS. A physical test fixture will be created for experimental validation. The software tool provides a resource for quick optimization of root fillet geometry in gear design.
