- 摘要:
- 设计了一种用于液体火箭发动机涡轮泵减振的环形颗粒阻尼器。为研究颗粒阻 尼器的减振性能,基于有限元法建立了附加颗粒阻尼器以及不加颗粒阻尼器的涡轮泵模型, 计算过程中采用结构阻尼系数来描述颗粒阻尼器的阻尼特性。仿真结果表明.颗粒阻尼器能 够显著降低涡轮泵的振动,并且对涡轮泵的动态特性影响很小。
- Abstract:
- A circular particle damper attached to the turbopump of the liquid rocket engine is designed.The models of the turbopump with and without the particle damper ale built with finite el— ement method to evaluate the damping effect on the vibration of the turbopump.In the simulation, the equivalent structural damping ratio is used to describe the damping performance of the particle damper.Numerical results show that the particle damper can reduce the vibration of the turbopump significantly,and has less effect on the dynamic characteristics of the turbopump.
