采用平面应力假设,给出了计算多环环间混杂复合材料飞轮的离心应力和初始极限转速的方法,并采用二维轴对称的有限元分析验证了计算方法的合理性,可作为初步设计多环环间混杂复合材料飞轮的依据.本文的算例分析还表明,无论单一纤维或混杂的复合材料飞轮,空心结构的初始极限转速和储能密度均高于相应的实心结构的结果;且对于空心结构,有利于通过选择合适的混杂方案,实现一定意义上的"等强度"设计. |

Based on the hypothesis of plane stress, a method is proposed for calculating the centrifugal stress and initial ultimate rotating speed of the multi-ring intermixing composite flywheel. 2D axisymmetric FEM is used to verify the effectiveness of this method. It can provide the reference for the elementary design of the multi-ring intermixing composite flywheel. The results also show that the initial ultimate rotating speed and energy-storage density of a hollow structural flywheel are both higher than of the solid structural flywheel of whether a single material or an intermixing material. As to hollow structures, it can realize an equal-strength design through the selection of a suitable material sequence. |
