摘　　要：根据弹塑性力学的基本理论 ,进行了复合材料飞轮转子的设计与分析 ,并通过有限元分析软件的数值模拟与分析 ,验证了弹塑性设计的有效性。作为算例的飞轮转子外直径 2 0 0 m m,轮环厚 4 0 m m,高 2 0 0 mm。在考虑塑性设计后 ,飞轮的极限转速提高了 2 9% ,达到 4 5 0 0 0 r/ m ,储能密度达到 14 0 W· h/The fundamental theory of elasticity and plasticity was represented and applied to the design and analysis of a composite flywheel rotor. Numerical simulation and analysis were represented by finite element method. The elastic plasticity design idea was conformed by the analysis results. The outer radial of flywheel rotor was 200 m and the thickness was 40 mm. The rim comprised press fitted multi ring for higher omega velocity. Consequently, the ultimate rotation speed of flywheel rotor increased from 32 000 r/min to 45 000 r/min, the stored energy of rotor was 4.15 kW·h and the specific energy density was 140 W·h/kg (0.48 W·J/kg).
