摘要
将非线性系统的刚度、阻尼分别展开为位移和速度的多项式级数，在导出广义频率响应函数的迭代计算公式的基础上，构造了实验条件下结构非线性物理参数的辩识方程，实现了在恒幅正弦扫描激励下对橡胶减振器动力参数的辨识，并对结果进行了讨论分析．
A procedure for non-linear dynamic parameter identification of rubber absorber is presented in this paper. The non-linear stiffness and damping forces are modeled with polynomial series functions of the displacements and velocities,respectively. Based on the iterative equation of general frequency response functions, the identifying equation under sinusoidal exciting is constructed. The result was discussed and satisfied.
