Finite element analysis program was used to calculate the stress of 300MW turbine rotor in straightening the axle,and the effect of each factor is analyzed combined with the trial result.
應(yīng)用有限元分析程序?qū)?00MW汽輪機(jī)轉(zhuǎn)子直軸進(jìn)行了應(yīng)力計(jì)算,并對(duì)各影響因素進(jìn)行了分析,結(jié)果表明退火處理過程中殘余應(yīng)力產(chǎn)生的塑性變形量不可忽略。
