Abstract

The inner and outer rotors of the contra-rotating propfan dual-rotor system, utilizing dual intershaft bearings, exhibit anisotropic support characteristics, whereas the vibration of the dual-rotor system is cross-coupled. This combination makes the identification of unbalanced responses and the efficiency of dynamic balancing challenging. To address this issue, this paper proposes a method for the dynamic balancing of the contra-rotating dual-rotor based on Harmonic Least Squares Method and Modified Initial Phase Vector (HLSM-MIPV). Firstly, a test bench for the contra-rotating dual-rotor system is constructed using two Micro-Electro-Mechanical Systems (MEMS) sensors. Secondly, unbalanced vibration vectors of the dual-rotor are identified using Harmonic Least Squares Method (HLSM). Thirdly, the Harmonic Component Method with the Modified Initial Phase Vector (MIPV-HCM) is introduced to balance the force and couple unbalance under anisotropic stiffness conditions. Finally, dynamic balancing tests on the test bench demonstrate that the MIPV-HCM method achieves an additional vibration reduction of 4 %–17 % compared to the traditional HCM.

HLSM-MIPV 逆旋转风扇双转子不平衡振动抑制算法

使用双轴间轴承的反向旋转推进器双转子系统的内转子和外转子表现出各向异性的支撑特性，而双转子系统的振动是交叉耦合的。这种组合使得不平衡响应的识别和动平衡的效率变得非常具有挑战性。针对这一问题，本文提出了一种基于谐波最小二乘法和修正初始相位矢量（HLSM-MIPV）的反转双转子动平衡方法。首先，利用两个微机电系统（MEMS）传感器构建了反向旋转双转子系统的测试台。其次，使用谐波最小二乘法（HLSM）识别双转子的不平衡振动矢量。第三，引入修正初始相位向量谐波分量法（MIPV-HCM）来平衡各向异性刚度条件下的力和耦合不平衡。最后，试验台上的动态平衡测试表明，与传统的 HCM 相比，MIPV-HCM 方法可额外减少 4 %-17 % 的振动。

期刊介绍： The Journal of Sound and Vibration (JSV) is an independent journal devoted to the prompt publication of original papers, both theoretical and experimental, that provide new information on any aspect of sound or vibration. There is an emphasis on fundamental work that has potential for practical application. JSV was founded and operates on the premise that the subject of sound and vibration requires a journal that publishes papers of a high technical standard across the various subdisciplines, thus facilitating awareness of techniques and discoveries in one area that may be applicable in others.
