基于流固耦合的压气机叶片结构分析

摘要

采用弱耦合的方式，通过workbench软件中的MFX- ANSYS/CFX耦合平台对涡轮增压器的压气机结构进行了仿真模拟。得到了在流体作用下压气机叶片的变形与应力分布情况，以及叶片的在不同转速下的各阶固有频率，为压气机的结构优化、控制叶片振动提供了理论依据。%By using weak coupling approach, simulation of the compressor structure of a turbocharger with the MFX-ANSYS/CFX coupled platform was made. The simulation produced deformation and stress distribution of the blade in fluid action and the natural frequencies of the blade at different speeds, providing a theoretical reference for compressor structure optimization and blade vibration control.
