摘　　要：为了解带冠航空发动机涡轮叶片的动态特性,利用UG软件建立了带冠叶片的简化模型,并导入ANSYS Workbench进行了网格划分、施加约束条件等有限元计算,得到了叶片的振动频率特性和振动模态特性,最后对涡轮叶片的强度计算和结构优化设计提出了一些合理的改进建议。To gain insights into the intrinsic vibration properties of turbine blades in aero-engines,this study focuses on establishing a simplified model of shrouded blades using UG software.Subsequently,the model is imported into ANSYS Workbench software for finite element calculations,encompassing grid division and constraint conditions.Through these calculations,the study successfully obtains the frequency characteristics and vibration modal properties of the blade model.The findings from this analysis facilitate the formulation of practical recommendations for enhancing the strength calculation of turbine blades and optimizing their structural design.
