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
