摘　　要：应用有限元软件计算了超(超)临界火电机组用闸阀在循环载荷下的峰值应力和谷值应力,通过应力波动值及使用次数计算了阀门的损伤系数,确定了阀门抗疲劳性能。To take the gate valve used by ultra supercritical thermal power unit as an example. Deter- mine the cyclic load of valve,the peak stress and valley stress under the cyclic load is calculated by fi- nite element software. The damage coefficient is calculated by stress fluctuation value and usage times to determine the anti - fatigue performance of the valve finally.
