Optimization Study on Folding Bicycle Frame Based on SolidWorks 2024

Abstract

With the acceleration of global urbanization, issues such as traffic congestion and carbon emissions have become increasingly severe. Consequently, folding bicycles have emerged as a major commuting option for urban residents. Nevertheless, the performance of many folding bicycles remains unsatisfactory. This study utilizes SolidWorks 2024 software to conduct 3D modeling, assembly, and mechanical analysis of folding bicycle frames. A 3D model (encompassing the top tube, down tube, main tube, front and rear forks, etc.) was constructed, and the Simulation module was employed to perform mechanical analysis on the frame made of 2014-T6 aluminum alloy. The optimal design was implemented by integrating principles of materials science and fluid mechanics. The research achieves frame performance enhancement from three aspects: Firstly, hollow design and thinner tubes are adopted in non-critical stress-bearing parts, while the structure and load-bearing capacity of high-stress parts are strengthened (reducing weight by approximately 35%); Secondly, the frame section is designed to be streamlined (minimizing the drag coefficient and windward area) to improve riding efficiency. Thus, the folding reliability and riding performance are optimized, and prospects for future performance improvement and material optimization (such as the application of carbon fiber materials and dynamic fatigue mechanical analysis) are proposed.
