摘　　要：转子是机械转动部件中的一种,存在于电动机、水轮机、风力发电机、飞轮储能系统等各种机电设备中。在飞轮储能系统中,转子的材料、形状等关键因素都会对系统的性能产生影响。文中以提高飞轮储能系统转子的转速为出发点,建立了复合材料转子的数字化模型,并且对芳纶纤维复合材料转子开展了有限元分析,确定了复合材料层数变化、过盈量变化等对轮毂和轮缘的径向应力、周向应力及转速的影响。数值模拟结果为芳纶纤维增强树脂基复合材料在复合材料飞轮中的应用提供了参考。The rotor is a type of mechanical rotating component that exists in various electromechanical equipment such as electric motors,water turbines,wind turbines,flywheel energy storage systems,etc.In flywheel energy storage systems,key factors such as the material and shape of the rotor can have an impact on the system's performance.To increase the rotational speed of the flywheel energy storage system rotor,this paper establishes a three-dimensional model of the composite material flywheel rotor,and conducts finite element analysis on the aramid fiber composite rotor,determines the effects of changes in the number of composite layers and interference on the radial stress,circumferential stress,and rotational speed of the wheel hub and rim.The numerical simulation results provide a reference for the application of aramid fiber reinforced resin matrix composites in composite flywheel materials.
