摘要
复合材料运用在飞轮体的制备上,极大地增强了储能飞轮的机械性能,并增加了单位质量中的动能储存效率。利用有限元分析理论结合各向异性弹性体基本理论建立复合材料储能飞轮力学模型,借助ANSYS有限元分析软件,对已知材料性能参数和转子主要形状尺寸的储能飞轮转子进行应力和位移分析,求出了在一定转速条件下转子的径向应力、环向应力和径向位移,对其分布规律进行探讨,为飞轮结构优化提供理论依据。
The composite materials can be applied to flywheel, which can reinforce mechanical behavior of energy storage flywheel and increase kinetic energy storage efficiency per unit mass. The mechanical model of composite energy storage flywheel is built based on the orthotropic elastic solid basic theory and the finite element theory. The distribution of radial and circumferential stresses as well as the radial displacement are analyzed, and the curve of the distribution has been drawn out. The results can be provided as a good reference while optimizing structure of flywheel.
