摘要: 采用有限元辅助进行碳纤维扭转轴定刚度设计，通过碳纤维缠绕成型工艺制备碳纤维扭转轴，并进行扭转刚度测试验证。结果表明，有限元计算得到碳纤维扭转轴扭转刚度为31.08 kN·m2/rad，实测碳纤维扭转轴扭转刚度为33.52 kN·m2/rad，设计误差为7.3%，该计算方法能够指导碳纤维扭转轴扭转刚度设计。与传统金属扭转轴对比，碳纤维扭转轴减重达到74.6%，减重效果明显。Abstract: Finite element analysis(FEA) method was used to design the stiffness of carbon fiber torsion shaft(CFTS). CFTS was prepared by carbon fiber winding process, and tested by torsion stiffness process. The results showed that the torsion stiffness of the CFTS obtained by FEA was 31.08 kN·m2/rad, that the torsion stiffness by testing was 33.52 kN·m2/rad, and that the design error was 7.3%. Therefore, the FEA method could guide the torsional stiffness design of CFTS. Compared with the traditional metal torsion shaft, the weight loss of CFTS reached 74.6%, demonstrating that the weight reduction effect of CFTS was obvious.
