摘要

摘要:
针对飞行状态下发动机转子振动超限问题，开展机动飞行状态下发动机转子-弹性阻尼支承系统的试验研究。模拟滚转、俯仰及偏航运动，角速度最高可达3.5 rad/s，研究由鼠笼弹支式挤压油膜阻尼器支承的多盘转子系统的动力学响应，测得轮盘位移、鼠笼应变、支座速度、油膜动压随不同机动动作及角速度的变化规律。结果表明：水平和垂直方向刚度异性，前两阶临界转速均有两个共振峰值；滚转或俯仰时，即使转子静止，鼠笼弹支也会在重力作用下发生周期性形变；位移、应变、速度、压力等信号都叠加了一个低频成分。俯仰、偏航引起的附加惯性力使轴系位移和应变分别沿着水平、垂直方向发生偏移，且随着角速度的增大，对应测点的偏移量越大。

Abstract:
To deal with the issue of engine rotor vibration exceeding the limits during flights, experimental research on the rotor-elastic damping support system during maneuvering flight was conducted. The rolling, pitching, and yawing motions were simulated, finding that the maximum angular velocities can reach 3.5 rad/s. The dynamic responses of a multi-disk rotor system supported by squirrel-cage squeeze film dampers were studied, indicating that the changes in disk displacement, squirrel-cage strain, support velocity, and oil-film dynamic pressure were measured with different maneuvering motions and angular velocities. The results indicated that due to the anisotropy of stiffness in both horizontal and vertical directions, there existed two resonance peaks in the first two critical speeds. In case of rolling or pitching, even if the rotor was at idle state, the squirrel-cage support could undergo periodic deformation owing to the gravity; and the signals of displacement, strain, velocity, dynamic pressure, etc, were all superimposed with a low-frequency component. The additional inertial forces caused by pitching or yawing motions caused the displacement and strain of the rotor system to shift along the horizontal or vertical directions, respectively; and as the angular velocity increased, the offsets of corresponding measurement points became greater.
