摘　　要：介绍了汽轮机叶片三维有限元应力分析系统，它具备完善的前、后处理和计算分析功能．采用三维八节点非协调单元进行计算，这种单元对于汽流力等弯曲载荷具有比三维八节点协调单元更高的精确度．分析系统具有易用、精确、直观的特点．对一个真实叶片进行了计算。A 3 D FEM stress analysis system of the turbine blade with perfect pre process and post process functions has been developed in this paper, and the 3 D incompatible block element with eight nodes is used in the calculation. This kind of element is more precise than the 3 D compatible block element with eight nodes when the bending load such as steam force exists. This system is convenient, precise and audio visual. Finally, the numerical computation results of a real blade are presented.
