| 摘 要： | 波纹管输运高速流体时经常会发生疲劳破坏,流体诱导波纹管振动是导致波纹管疲劳破坏的重要因素之一.通过归纳总结国外相关研究成果,阐述了流体诱导振动的机理：液体诱导波纹管振动属于漩涡脱落诱导振动;气体诱导波纹管振动属于声振荡-弹性耦合振动.根据研究结果提出了抑制振动的措施.

| Abstract: | Fatigue failure of bellows occurs quite often when they carry fluids at high speed. Fluid-induced vibration is one of the important factors of the fatigue failure. In China, there is less research on this problem at present. The relevant research achievements abroad are summarized in this paper. The mechanism of flow-induced vibration is introduced. The liquid-induced vibration of bellows belongs to the vortex shedding induced vibration, while the gas-induced vibration of bellows belongs to acoustic and elastic coupling vibration. The vibration suppression measures are proposed in this paper on the basis of the research achievements. |
