摘　　要：使用三维电磁有限元分析技术,建立了便于工程实际应用的多壁碳纳米管(MWNTs)在树脂中电场取向扭转分析数值模拟方法。该方法利用连续体等效体理论,建立了MWNTs等效实体分析模型,模型考虑了MWNTs线状圆柱及非线状圆弧两种不同材料结构特征,理论计算与模拟结果吻合较好。该方法可为电场取向碳纳米管增强树脂复合材料工艺制备参数的优化设计提供理论依据。The numerical simulation method of the orientation torque analysis of multi-walled carbon nanotubes （MWNTs） under the electric field in the resin was established to facilitate the practical application of engineering, which used the three- dimensional electromagnetic finite element analysis techniques. The continuum equivalent theory was utilized in the method to establish an equivalent entity analysis model, considering the linear cylindrical and non-linear arc MWNTs. The simulation results are in good agreement with the theoretical calculation. This method contributes to provide a theoretical basis of the optimal design of process parameters of fabricating the oriented carbon nanotubes reinforced resin composites.
