| 摘 要： | 在＂自由-自由＂边界条件下,对导弹弹身和舵传动系统进行模态试验,采用多参考最小二乘复频域（PolyMax）法对结构模态参数进行识别。结果表明该方法对于小阻尼线性结构和大阻尼非线性结构（系统）,都能够很容易实现准确的模态定阶,并获得精确的模态参数。

| Abstract: | The modal tests are made for a missile body and a rudder transmission system under ＂free-free＂ boundary conditions.The modal parameters are estimated with the Least Square Complex Frequency（PolyMax） method.The results indicate that the modal parameters obtained by this method are more accurately and easily in cases such as lowly damped linear systems and highly damped nonlinear systems. |
