摘要:
以折叠电动车主折叠机架为对象,利用有限元对其进行轻量化设计.运用Solid Works建立主折叠机架的简化三维模型,导入到ANSYS Workbench中进行静力学分析,并利用拓扑优化和尺寸优化的方法对主折叠机架连杆进行轻量化设计.结果表明:原始折叠电动车主折叠机架在3种工况下有可优化的空间,进行拓扑优化后主折叠机架由10.97 kg变为10.48 kg,减轻了4.47%;对拓扑优化后的结构进行力学分析,发现主折叠机架还有进一步优化的空间.在拓扑优化的基础上,通过尺寸优化的方法对主折叠机架的槽型折弯件的截面尺寸进行轻量化设计,其质量变为8.72 kg,两次优化主折叠机架共减轻了20.51%,轻量化效果明显.
Abstract:
Taking the main folding frame of foldable electric vehicle as the research object, the lightweight design was carried out by using the finite element method. The simplified three-dimensional model of the main folding frame was built with SolidWorks and analyzed in ANSYS workbench. The lightweight design of the main folding frame connecting rod was realized by using topology optimization and dimension optimization. The results showed that the original folding electric vehicle rack had space for optimization under three working conditions, and the quality of the main folding rack was decreased from 10.97 kg to 10.48 kg, the weight reduction of which is 4.47%. The mechanics analysis of topology optimization structure indicates more optimization space in main folding frame. On the basis of topology optimization, the section size of groove bending parts of main folding frame was lightened by size optimization method. The quality of main folding frame decreased to 8.72 kg and lightened 20.51% in total after two optimization steps. The lightweight effect was very obvious.
