正弦激励用于非线性系统参数辨识

Non Linear Structural Parameter Identification Using Sine Excitation Method

正弦激励广泛用于结构非线性检测，将该方法推广到系统参数辨识领域，使得被测结构仅在一次恒幅正弦扫描激励试验下即可直接辨识得到系统全部非线性物理参数。

Sine excitation method is widely used in the dynamic structure non linear detecting. This paper developed the method to the field of parameter identification. It makes the identification of the structure non linear physical parameter easy and direct at only one time invariable amplitude sine sweep measurement, and makes the testing procedure more simple.
