Analysis of the vibration modal of a ram-compressed rotor of rotating ramjet

    Abstract
  • The finite element model of ram-compressed rotor is established with the finite element analysis software ANSYS.The rotor structure is analyzed,and the first ten oscillating frequency and oscillating modal are obtained.The rigidity support is compared with elasticity support.The result shows that the drafted working speed effectively avoids the first critical speed.The results can provide a good foundation for further dynamic research of the structure of rotating ramjet.
