Abstract: [Objective] To explore the use of lightweight design method to improve the performance and efficiency of automobile drive shaft. [Method] Taking flange fork, spline shaft fork and universal joint fork as the research objects, a structural design method based on density for topology optimization has been proposed. Mechanical analysis is carried out on the built model. Based on the analysis results, optimize possible issues, and mechanical check tests are carried out on the optimized parts again until they meet the safety requirements. [Result] The design scheme performed better than the existing schemes, and the final scheme reduced the quality of the drive shaft by about 18%. [Conclusion] The optimized approach provides a practical and effective method to reduce weight, which can also be used to reduce the weight of instruments, reduce energy consumption and improve the environment.
