摘要
为提高飞轮的储能密度,需采用合适的转子材料和合理的转子结构。复合材料与各向同性材料相比具有明显优势。多层转子结构突破了单层转子内外半径比的限制,可明显改善转子内部的应力分布,提高飞轮的储能密度。该文论述了复合材料飞轮储能密度的影响因素,对复合材料转子的应力分布作了定量分析,比较了单层和多层转子的特点,综合考虑飞轮设计的各种因素,提出了飞轮转子结构参数的设计方法。
In order to increase energy-storing density of flywheel, appropriate rotor material and reasonable structure should be used. Compared with isotropic materials, the composite material has evident advantages. Multi-ring rotor structure breaks through restriction of the ratio of inner radii to outer radii, which can evidently improve the distribution of rotor stress and increase flywheel energy-storing density. This paper discusses the influence factor in the energy-storing density of composite flywheel, quantificationally analyzes the stress distribution of composite material rotor, and compares the characteristics of single-ring with multi-ring rotor. Synthetically considering all these factors, a design method of flywheel rotor structure parameters was put forward.
