中文摘要：
不同的边界条件对复合材料飞轮的应力、位移分布有着不可忽视的影响，和飞轮的储能密度也有相当的关系。针对复合材料和对称结构的特点，建立基于非均质各向异性弹性理论的计算模型，得到飞轮在工作转速情况下应力和位移计算的解析公式，给出了任一点的径向、环向应力及径向位移。并按照所建立的计算模型对飞轮的几何尺寸、转速对其应力、位移场的影响进行仿真计算，并对不同的边界条件对飞轮径向、环向应力和径向位移的影响进行比较。
英文摘要：
For composite flywheels, different boundary conditions often have important effects on the stress and displacement distributions and are fairly related with the energy storage density. According to the character of composite and symmetrical structures, a calculation model was founded based on the nonhomogeneous anisotropic elastic theory, analytic formulas of stress and displacement for composite flywheel at working speed were given to gain radial stress, circumferential stress and radial displacement of arbitrary point. According to the computation models above, the influences of different dimensions and rotational speeds on stress and displacement field were simulated and the influences of different boundary conditions on radial and circumferential stresses and radial displacement for flywheel were compared.
