摘要
飞轮转子是飞轮储能系统(FESS)中的重要部件。飞轮转子的材料、几何形状和制造工艺等关键因素都会对FESS的性能产生直接的影响。采用三维有限元方法,分析了金属轮毂与纤维缠绕成型的复合材料轮缘结构的飞轮转子,在16 000 r/min的转速下,转子材料、轮毂与轮缘的安装方式以及缠绕角对金属轮毂Von Mises等效应力分布和复合材料轮缘径向应力分布的影响。根据分析结果,确定了复合材料飞轮转子的制造工艺:T800H碳纤维复合材料轮缘在7050铝合金轮毂上直接缠绕成型,飞轮转子能够正常工作。
Flywheel rotor is a very important component in the flywheel energy storage system ~ r rJ33）, lne Key factors of rotor, such as rotor materials, geometry and fabrication process, have direct influence on the performance of FESS. This paper was concerned with influences of these factors on the Von Mises equivalent stress distribution of the metal hub and the radial stress distribution of the composite materials rim by using the 3D finite element method. The fabrication process of the flywheel rotor was determined based on the analysis results： T800H carbon fiber composite materials rim was formed by winding on the 7050 aluminum alloy hub. The flywheel rotor developed can operate normally.
