摘要
利用有限元法对一种典型超临界机组汽机高中压转子的冷态启动做初步的分析,找到转子的温度分布与变化规律,求出其瞬态热应力变化,给出启动建议.
Based on preliminary analysis on steam turbine unit by finite element method, out and instant state thermal stress change presented. cold start-up of HIP rotor of typical super critical temperature profile and variation laws are found is calculated. Therefore the start-up proposal is
