摘要:
提出了考虑材料物性随温度变化的疲劳寿命算方, 对比了在考虑材料温度特性及不考虑材料温度特性情况下对汽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效提高计算结果的精度.
Abstract:
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. 
