摘要
[目的]探究使用轻量化设计方法提高汽车传动轴的性能和效率。[方法]以传动轴的三个关键部件凸缘叉、花键轴叉以及万向节叉为研究对象,提出了以密度为基础进行拓扑优化的结构设计方法。对建好的模型进行力学分析,根据分析结果,对可能存在的问题进行优化,并对优化的部件再次进行力学校核测试,直至符合安全要求。[结果]该设计方案较已有相关方案表现优异,最终方案使传动轴的质量降低了约18%。[结论]该优化方式为减轻重量提供了一种切实有效的方法,也可用于减轻器械重量、降低能源消耗和改善环境。
[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.
