摘要
本文给出一种方法,可利用谐波平衡原理对受到库仑摩擦的振动系统进行参数识别,并通过实例说明了该方法的计算过程和参数识别的精度。
This paper has presented a method for parameter identification of vibratory systems subject to Coulomb's damping forces by the use of the harmonic balance principle and illustrated with two examples the calculation process for the method and the precison of parameter identification.
