| 摘 要： | 由于有限元单元类型的选择、网格划分精细程度上的不同,同一个模型的分析结果会有不同。本论文结合某型航空发动机叶片模态分析的实例,分析了单元类型的选择和网格划分精细程度的高低对分析结果精度的影响;揭示了随网格划分精细程度的变化,分析结果的收敛规律;并用有理论解的悬臂梁验证了收敛规律。

| Abstract: | The modal analysis of the same model is variable with different element type and meshing quality.This paper takes the aero-engine blade modal analysis as a calculating example to investigate the effect of different element types and meshing quality on modal analysis results.The convergence law that the analysis results change with different meshing quality is presented,and it is verified with theoretical solution of the cantilever. |
