摘要

本文主要研究了利用CAD软件获取喷气发动机iSTC-21v涡轮叶片固有频率的可能性。文章的第一部分是基于真实涡轮叶片的精确三维涡轮叶片几何图形CAD建模和叶片网格划分的可能性。该贡献突出了使用ANSYS APDL和Creo simulation计算高涡轮叶片固有频率的可能性。另一个目的是根据涡轮叶片固有频率的最终计算值对各个软件进行比较。任务是将结果的质量与特定程序中求解和创建数学有限元模型所需的时间进行比较。在固有频率方面的结果是必要的适当的喷气发动机运行。在喷气发动机工作范围内，固有频率不能与激励频率一致。结果可用于创建坎贝尔图。

FEM analysis of natural frequencies of jet engine iSTC-21v turbine blade

the paper is focused on possibilities of obtaining natural frequencies of jet engine iSTC-21v turbine blade using the CAD software’s. First part of the article is devoted to the possibility of exact 3D turbine blade geometry CAD modeling and blade meshing, which is based on real turbine blade. The contribution highlights the possibilities of using ANSYS APDL and Creo Simulate for calculating the natural frequencies of high turbine blade. Another aim is to compare individual software based on final calculated values of turbine blade natural frequencies. The task is to evaluate the quality of the results in comparison to the required time for solution and creation of the mathematical finite element model in particular programs. The results in terms of natural frequencies are necessary for appropriate jet engine operation. Natural frequencies cannot be with excited frequency in operational range of jet engine. The results can be used to create Campbell diagram.
