摘　　要：针对储能飞轮充放电实际运行过程,基于弹性力学理论,采用平面应力假设,考虑角加速度的影响,对复合材料飞轮转子进行应力分析。对照恒转矩和恒功率两种充放电控制方式,分别建立飞轮转速的变化模型,并以此为基础得到飞轮充放电过程应力变化规律,为安全合理设计飞轮转子提供重要参考。Based on elasticity theory, using plane stress assumption, considering the effect of angular acceleration, stress analysis of the composite flywheel body in charging-discharging process of the actual operation was carried out. For two kinds of charge-discharge control modes, constant torque and constant power, and the flywheel speed change models were established, respectively. Based on them, the regularity for stress change of the flywheel char- ging-discharging process was acquired, and used as a significant reference for designing safely and reasonable flywheel .
