摘要
本文在文献［１］所提出的基于正交性条件识别机械结构结合面阻尼参数方法的基础上，进一步提出采用正交条件式中虚部方程识别结合面动力学参数的方法。理论和算例分析表明这种改进方法能大大降低机械结构的物理参数（即质量、阻尼和刚度）矩阵和结构系统测试振型二者的误差对结合面参数识别精度的不利影响，从而使这种方法更具有可行性。
Based on the method of reference , an improved method has been developed which identifies the mechanical structural joint parameters using the imaginary part equations of the orthogonality relation equations. The numerical examples show that the disadvantage effects of the errors in both the analytical model and test values on the identifying precision can be reduced greatly with this new method. The validity of the presented method has been demonstrated through a practical radial drilling machine model.
