| 摘 要： | 将谐响应分析法应用于汽轮机叶片的动应力分析。首先用有限元方法对汽轮机叶片进行模型简化并计算出叶片的动频，然后应用模态叠加谐响应分析计算出叶片位移的动态响应，进而对位移动态响应进行扩展分析求得叶片的动应力。 |
| 关 键 词： | 汽轮机 叶片 动应力 谐响应分析法 模态叠加法 振型 |

| Abstract: | The method of harmonic response analysis is applied to the analysis of dynamic stress of steam turbine blade in this paper. First the steam turbine blade is modeled and its dynamic frequencies are calculated by using the finite element method. Then, the dynamic response of displacements of blade is computed by using the harmonic response analysis method of modal superposition, after that, the dynamic stress of blade is obtained by the expansion analysis of dynamic responses. |
| Keywords: | harmonic response method of model superposition model shape steam turbine blade dynamic stress |
