摘要
阐述了载荷谱下汽轮机转子疲劳寿命的计算方法,推导出计算转子瞬态温度场弹塑性应力场的有限元方程,并编制了程序。用该程序计算了200MW汽轮机转子在几种启、停工况下的温度分布,最后计算了该转子在调峰载荷谱下的疲劳寿命消耗。
An estimation of turbine rotor fatigue life during load change is presented.The finite element constitutionequations of transient temperature and thermal-elastic-plastic stress field are derived as well as the computer program.Thetemperature and stress field of 200 MW turbine rotor under different start-up and shut-down conditions are calculatedusing this program.The expenditure of rotor fatigue life during 30years cycling period is calculated also.
