Identification of the Stiffness and Damping Parameters for a General Joint

针对两侧均为弹性体的一般结合部，提出了一种基于实验模态参数的结合部刚度与阻尼参数的辨识方法．特别地，当弹性体内与结合部上存在部分难测模态分量时，给出了相应的辨识算法．该方法具有计算简单，易于编程，辨识精度好，实用性强等特点．

An identification method of the stiffness and damping parameters exploiting theexperimental model parameters is presented for a general joint, both sides of which are elasticbodies. Expecially,the corresponding identification algorithm is given to the case that there arepartial components of model vector in the elastic bodies and on the structural joint, which aredifficult to be measured. This algorithm is simple, ease to be compiled,good in identificationaccuracy and perfect in practice.
