基于ANSYS Workbench对航空发动机外部管路进行仿真分析。针对直管型管路、90?型管路、S型管路、Ω型管路及其不同壁厚,对管路固有频率、模态以及振动响应进行了分析。仿真分析结果表明,随着管路壁厚的增加,管路的固有频率也逐渐增加。直管型管路、S型管路、Ω型管路振动响应较小,90?型管路振动响应较大。分析结果为航空发动机外部管路优化设计提供了一定的依据。
The external pipelines of aeroengine were analyzed based on ANSYS Workbench. The natural frequency, mode and vibration response of straight pipes, 90? pipes, s-pipes, Ω pipes with different thickness were analyzed. The simulation results show the natural frequency of the pipelines increase with the thickness of the pipelines. The vibration responses amplitude of straight pipeline, s-pipes and Ω pipes are smaller, but the vibration responses of 90? pipelines are larger. This simulation results provide a bit of basis for the design and optimization of aeroengine external pipelines.
