为了调整某轻型单轴式燃气轮机转子支承系统临界转速和控制振动，理论计算和实验分析了该燃气轮机转子支承系统动力特性。结合该燃气轮机的具体结构，设计了弹性支承和多孔质挤压油膜阻尼器（ＰＳＦＤ），调整其临界转速和控制振动。将弹性支承和ＰＳＦＤ安装在该燃气轮机上进行开车实验的结果表明，理论计算与实验结果吻合得很好，临界转速调整到了预期值，阻尼器的减振效果突出。弹性支承和ＰＳＦＤ在实际燃气轮机上获得了成功应用。
In order to adjust the critical speed and the control vibration of a light-weight single-shaft gas turbine rotor support system, the dynamic characteristics of the gas turbine rotor support system are theoretically calculated and experimentally analyzed. Combined with the specific structure of the gas turbine, a flexible support and a porous squeeze film damper (PSFD) are designed to adjust the critical speed and the control vibration. The results of driving test with elastic support and PSFD mounted on the gas turbine show that the theoretical calculation is in good agreement with the experimental results, the critical speed is adjusted to the expected value, and the damping effect of the damper is outstanding. Elastomeric bearings and PSFDs are successfully used on actual gas turbines.
