考虑到材料温度特性的汽机转子疲劳寿命计算

Calculating the Cyclic Life Expend Considering the Change of Material Characteristic with Temperature

提出了考虑材料特怀随温度变化的疲劳寿命算法，对比了在考虑材料温芳特性及不考虑材料温度特性情况下民轮机转子在启动过程中的寿命损耗计算结果的差异，证明考虑材料温度特性的计算方法能有提高计算结果的精度。

This paper provides a new calculating method for the cyclic life expend by considering the change of material characteristic with temperature. Compared with the results by the earlier method, the calculation precision by this method can be raised markedly.
