摘要： 根据阻抗耦合子结构法的基本原理，提出基于阻抗耦合子结构法求解电主轴固有特性的流程，包括电主轴轴段的划分、根据Timoshenko梁理论求解各轴段固有频率和各轴段频响函数、电主轴的阻抗耦合、结果分析等步骤。以某立式加工中心电主轴为研究对象，应用所提出的方法，对该电主轴的固有特性进行求解，并与有限元分析结果对比，证明了该方法的有效性。

Abstract: Based on the theory of receptance coupling substructure analysis，the solving process of inherent characteristics were proposed，which included the division of spindle shaft segment，the inherent frequency and frequency response function in each segment solved by Timoshenko beam theory，the impedance coupling of the spindle，result analysis and so on.By taking the motorized spindle of a vertical machining center as object，its inherent characteristics were solved by proposed method.The result revealed the effectiveness of the method by comparing with finite element analysis.
