| 1 | A novel none once per revolution blade tip timing based blade vibration parameters identification method显示文摘The vibration caused blade High Cycle Fatigue(HCF)is seriously affects the safety operation of turbomachinery especially for aero-engine.Thus,it is crucial important to identify the blade vibration parameters and then evaluate the dynamic stress amplitude.Blade Tip Timing(BTT)method is one of the promising method to solve these problems.While,it need a high resolution Once Per Revolution(OPR)signal which is difficult to get for the aero-engine.Here,a Coupled Vibration Analysis(CVA)method for identifying blade vibration parameters by a none OPR BTT is proposed.The method assumes that every real blade has its own vibration performance at a given speed.Whereby,it can take any blade as the reference blade,and the other blades using the reference blade as the OPR for vibration displacement calculating and further parameter identifying.The proposed method is validated by numerical model.Also,experimental studies are carried out on a straight blade and a twisted three dimensional blade test rig as well as a large industrial axial compressor respectively.The results show that the proposed method can accurately identify the blade synchronous vibration parameters and quantitatively evaluate the mistuning in bladed disks,which lays a foundation for the reliability improvement of aero-engine. | Weimin WANG Xulong ZHANG Dongfang HU Dengpeng ZHANG Paul ALLAIRE | 2020 | Chinese Journal of Aeronautics2020，33，7： | 6 |
| 2 | 汽轮机-齿轮箱-发电机系统中大型次同步振动问题的轴承解决方案(英文)显示文摘运转速度为10,700rpm的西门子12MW工业高速汽轮机驱动弗兰德公司的齿轮箱小齿轮,该齿轮箱与低速齿轮轴相连,齿轮速比17.1,以1500rpm(50Hz)的速度驱动西门子发电机。在较低的电气载荷下,高速小齿轮中出现了0.89倍的高振幅亚同步振动。Zollern齿轮箱小齿轮轴承由两个半偏置、两瓦块轴承组成,这些轴承被发现不稳定,在0.89倍工频下激发一种小齿轮轴-汽轮机轴模式。导致该问题的一个因素是机油泄漏到高速联轴器中。由于齿轮箱小齿轮中的可用轴承空间有限,无法使用可倾瓦轴承来解决问题。设计了带有三个瓦块和两个油楔的轴承来解决该问题。使用这种方法消除了在0.89倍工频下的振动问题。这篇文章阐述了转子特性分析和新轴承的设计过程。 | Paul Allaire Tim Dimond Jianming Cao | 2019 | 风机技术2019，61，6： | 3 |
