摘要
详细介绍了雨流法基本原理及其计算模块的编制。将该模块并入电厂汽轮机转子寿命损耗监控软件中,能够真实地反映监控部位的应力时间关系,对提高机组安全性、正确指导机组起停、变负荷运行有重要意义。
The basic principle and workingup of calculating module for the rainflow method have been presented in detail. Incorporating the said module into monitoring software for service life consumption of turbine rotor in the power plant, the stresstime relationship at the monitoring point can be actually represented, having important significance for enhancing the safety of unit, correctly guiding the startup and shutdown, as well as varying load operation of the unit.
