摘　　要：高速复合材料飞轮是飞轮储能技术的发展趋势,而纤维缠绕型飞轮径向强度低、易脱层。该文将多层层间混杂飞轮发展为多层层内混杂飞轮,在飞轮径向实现压应力,解决了径向脱层问题。基于混合律得到材料的弹性常数,建立单层和多层复合材料飞轮的力学方程,考察横向拉伸模量对应力与变形的影响。设计并制作了6层层间混杂飞轮,并基于频闪光源同步转子的变形光学测量方法完成了旋转变形测试。结果表明:混杂设计方法灵活可行,变形测试方法测量结果与理论值符合程度较高。The high-speed composite flywheel is the core component of advanced flywheel energy storage systems. However,the traditional filament winding flywheel can experience delamination due to the low radial strength.An intra-ply commingled composite flywheel,which was similar to a multi-layer hybrid flywheel,was designed to produce a radial compressive stress to eliminate the delamination.The mixed law was used to obtain the elastic constants to establish mechanical equations for a single layer and a multi-layer composite flywheel to assess the influence of the transverse tensile modulus on stress and deformantion. A 5-layer commingled composite flywheel was analyzed with elasticity theory with a parametric study conducted to identify the relationship between the hierarchical number,the stress,and the deformation.A 6-layer inter-ply commingled composite flywheel was manufactured and the rotation deformation was measured with the optical deformation measurement method using a synchronous strobe light.The results verify that the commingled flyweel design is feasible and the deformation measured with the optial deformation method conforms well with the theoretical value.
