中文摘要:
      为抑制叶片-盘耦合振动,设计了一种适应整体叶盘结构的环形摩擦阻尼器。拓展了1阶谐波平衡法和整体-局部统一滑动模型在带环形摩擦阻尼器的循环对称结构叶盘减振分析中的应用。使用该方法对实际发动机叶盘在简谐激励下的振动响应进行了仿真计算,结果表明:环形摩擦阻尼器对于某发动机叶盘的0节径4阶危险模态振动有明显抑制作用,且减振效果与阻尼器的质量、安装位置有关,在选定的安装位置最高可使振幅降低75%。在阻尼器结构确定的情况下,利用仿真结果给出了最优的设计方案,包括阻尼器的质量和安装设计。
英文摘要:
      A kind of annular friction damper adapted to the blisk was designed to control the blade-disk coupling vibration. The first-order harmonic balance method and the macro-micro slip model were expanded to the cyclic symmetry model to simulate the vibration reduction of blisk with ring damper. Results of simulating realistic blisk showed that the annular friction damper had obvious effect on the 0-diameter 4th-order dangerous modal vibration of the blisk, and damping effect was related to the quality of the damper and the installation position. The amplitude was reduce by 75% at the selected location. The optimal damper design, including mass and installation design, was established when its structure was determined.
