THERMAL STRESS EXPECTATION OF A CZECH-MADE 500 MW TURBINE IN SHENTOU POWER PLANT[J]. Thermal power generation, 1998, (3): 21-25. DOI: 10.19666/j.rlfd.1998.03.005.
神头二电厂捷制500MW机组的热应力预测
摘要
在预先知道或通过有限元法求得捷制 5 0 0MW机组的高、中压转子的最大应力点后
着重对该处的热应力进行监控
并采用较为简单的方法
将复杂传热简化为一维不稳定导热问题
对该危险部位的热应力进行全过程的计算
从而得到了该部位的应力变化规律。
Abstract
Monitoring was made on the maximum thermal stress points on HP and IP rotors of a 500MW turbine by the finite element method.Meanwhile
by simplifying the complicated heat transfer into a unstable one-dimentional heat conduction
a calculation of process was conducted on these critical pionts to obtain the rules of stress changes
