Abstract
With the rapid development of modern industry, the demand for performance and efficiency in mechanical products has increased significantly, making lightweight technology a crucial research direction in mechanical design. This study aims to explore lightweight technologies in mechanical design to achieve ob jectives such as weight reduction, energy conservation, and performance enhancement. By conducting mechanical property analyses of various lightweight materials including high-strength steel, aluminum alloys, magnesium alloys, and composite materials, combined with finite element simulation and practical testing, this research systematically investigates the application effects of different materials in mechanical structures. An innovative structural design method based on topology optimization algorithms is proposed, achieving maximum weight reduction while ensuring structural strength. The results indicate that integrating novel lightweight materials with optimized design can reduce the weight of typical mechanical components by 20% to 40%, while increasing overall structural stiffness by more than 15%. Additionally, the application of this technology effectively reduces manufacturing costs and improves production efficiency. This research not only provides new ideas and technical means for mechanical design but also makes a positive contribution to energy conservation and emission reduction in related industries, demonstrating significant theoretical implications and practical value.
