| 摘 要： | 讨论了一种滑动轴承动力系数实验识别的广义逆矩阵法，滑动轴承动力系数不是可以直接测量的物理量，它们只能从测得的转子－轴承系统的动态响应函数中采用参数识别方法求得．因此一种有效的参数识别算法在轴承动力系数的测试中起着十分重要的作用，本文提出的广义逆矩阵识别方法具有高效、简单和可靠等优点．文中给出了一个数值实例以证实本方法的有效性．

| Abstract: | An identification method for experimental determination of the dynamic coefficients of the oil film hydrodynamic journal bearings using generalized matrix inversion is presented. The dynamic coeffcients of the journal bearings are not directly measurable parameters. They can only be identified from dynamic response functions of the measured system. The identification method presented in this paper has the advantages of efficiency, simplicity and reliability. An example is given at the end of the paper. |
