摘要
本文提出一种识别动力字系统中结构振动模态参数的新方法，即围形法识别振动模态参数。该方法以三次B—SpLine、Bezier、三次多项式样条以及自由曲线面等为基本工具，构成一套对动力字系统的模态参数进行快速、直观地识别的新颖方法。
In this paper, we put forward a new method which can identify the structure vibrated modal parameters for the dynamic system, i. e. identification of vibration modal paranoters by drawing method. A novel method that can fant and directly idertify the modal parame ters for the dynamic system is set by using cubic B-Spline, Bezier, cubic Polygons Spline and free form curves and surface.
