【摘要】 传统的平衡方法对于具有显著各向异性转子的不平衡响应会产生测量和评价上的误差。从信息融合的视角,分别在忽略和考虑了非线性因素两种情况下对各向异性转子的不平衡响应的规律进行研究。在全矢谱理论和传统影响系数法的基础上,对各向异性转子采用双传感器信息融合的方法进行不平衡响应的测量。通过实验来验证动平衡中各向异性的存在及其对不平衡响应的影响,和全矢动平衡技术对平衡各向异性支撑转子的有效性,为新的动平衡方法研究提供理论上的依据。更多还原

【Abstract】 The traditional balance methods for significant anisotropy of rotor will produce the error of the measurement and evaluation. The changing law of anisotropic rotor’s unbalance response was researched on the conditions of ignoring and considering about nonlinear stiffness coefficients respectively from the angle of information fusion. Anisotropic rotor’s unbalance response was measured by information fusion with double sensor on the basis of the full vector spectrum theory and traditional influence coefficient method. The existence and impact of the anisotropy and the validity of full vector dynamic balancing for anisotropic rotor in balancing are verified through the experiment. This result provides theoretical basis for the study of the new method of dynamic balance.更多还原
