| 摘 要： | 分析了目前的叶片减振技术，设计开发了一种叶片闭环可控吸气减振系统，在叶片振动试验台上完成了对比实验，测试了减振系统的减振效果。实验过程中，系统实时监测叶片的振动情况，当叶片振动超过预先设定的门槛值时，系统自动地采取吸气减振措施，降低叶片振动。实验表明，当叶顶是光滑密封时，减振系统能使叶片振动减少16％; 当叶顶是蜂窝密封时，减振系统能使叶片振动减少15.3％。

| Abstract: | Current technologies for vibration reduction of blades are analyzed.A vibration reduction system using closed-loop control air-inhalation technology has been developed.Comparative experiments were carried out on a blade vibration experimental rig,and the vibration absorbing ability of the system was tested.During the experiments,blade vibration was monitored in real time,and when the vibrations exceeded the pre-set safety value,the system reduced the vibrations automatically.The results showed that blade vi... |
