An interactive web-based spur gear design tool based on AGMA standards for engineering education and preliminary design

Abstract

This paper presents the development and evaluation of an interactive web-based tool for spur gear design based on ANSI/AGMA 2001-D04 standards. The platform integrates gear geometry, load analysis, bending and contact stress calculations, and safety factor evaluation within a unified and accessible environment. Designed as both a computational and educational resource, the tool enables real-time parameter modification and immediate visualization of results, facilitating efficient and error-free design processes. The accuracy of the tool was validated against analytical solutions and standard references, demonstrating strong agreement. Its educational effectiveness was assessed through a survey of 34 graduate mechanical engineering students, with results indicating high levels of usability, improved conceptual understanding, and strong preference over traditional manual and spreadsheet-based methods. The interactive features, particularly real-time feedback and graphical visualization, were identified as key factors in enhancing learning and bridging the gap between theory and practice. Furthermore, the integration of the tool significantly expands the alignment of the gear design topic with ABET outcomes. The tool enables the gear design chapter to contribute to all Course Learning Outcomes (CLOs) and supports all seven Program Learning Outcomes (PLOs), including problem solving, design, communication, experimentation, and lifelong learning. The results demonstrate that web-based interactive tools can effectively enhance both engineering design practice and education. The proposed platform offers a scalable and accessible solution for modernizing machine design instruction and supporting outcome-based learning.
