汽轮机低周疲劳损伤的快速估算方法

摘要

In this paper, the Neural Net Expert System method for turbinelife estimation which is based on the finite element analysis result is presented. It combined the Neural Net with generation system for turbine life estimation and the basic theory structure was set up, then a system test was held by using finite element calculation. The result prove that this method is feasible and it is fast, accurate and flexible.%结合产生式专家系统和BP神经网络的特点，提出了基于有限元计算的汽轮机低周疲劳损伤和寿命估算神经网络专家系统方法，建立了系统框架，并进行了系统测试。测试结果表明，该方法是可行的且具有快速、准确、灵活的特点。
