摘要

整机动平衡相较传统工艺动平衡可大幅提高整机不平衡振动控制效率；由于发动机振动测点位于薄壁机匣支承结构表面，无法直接测得轴承位置的不平衡响应矢量，使整机动平衡难度增大。为此，提出一种基于机匣外部测振信号的轴承位置不平衡响应矢量逆推方法；虑及薄壁机匣支承结构动力特性的影响，通过仿真分析结合试验获得测点振动响应与轴承位置不平衡激励之间的影响函数矩阵；利用该函数矩阵及机匣外部振动测点实测响应逆推轴承位置不平衡响应矢量。通过对典型双转子发动机高保真机匣系统的数值仿真分析，验证了该方法的有效性；对于实现发动机转子不平衡矢量逆推以及整机振动控制具有工程应用价值。

Abstract

The efficiency of controlling unbalance vibration of gas turbines can be greatly improved by overall maneuver balance compared with the traditional process.However, since the measuring points of vibration can be only located on the surface of the thin-walled casing structure, the unbalance response of the bearing position cannot be directly measured, which makes the overall maneuver balance more difficult.Therefore, an inverse method for calculating unbalance response vector of bearing position based on external vibration signal of casing was proposed in this paper.Considering the influence of the dynamic characteristics of the thin-walled support structure, the influence function matrix between the vibration response of the measuring points and the unbalance excitations of the bearing position was obtained through numerical simulation combined with tests.The unbalance response vector of the bearing position was inversely calculated by using the function matrix and the vibration of the casing measurement point.The method was validated by numerical simulation results of a high-fidelity thin-walled casing model of a typical double-rotor engine.This method has certain application value for reversely calculating rotor imbalance vector and vibration control of engines.
