| 摘 要： | 在大量的转子引水拐脚疲劳强度分布试验基础上，根据引水拐脚的应力分析计算结果，对双水内冷３００ＭＷ组汽发电机组在设计寿命内，二种型式引水拐脚的疲劳损伤进行了计算分析，以其疲劳寿命的可靠度进行了估算，验证了拐脚安全运行的可靠性。为转子引水拐脚的造型，设计，优化及工艺制定提供了理论依据。

| Abstract: | Two types of lead connection's fatigue damage and life reliability prediction within designed life to the rotor of turbogenerator with a double water internal cooling system have been discussed and estimated, by means of both of experimental and analytical result of stress distribution, based on a large quantity of fatigue strength distribution tests. The reliability to assure safely operation are also studied here. These results are to be used in the lead connection's profile design, structural optimization and technology plan. |
