| 摘 要： | 研究了振动反问题,提出了一种适用于振动系统参数识别的迭代方法。该方法把振动控制方程转化为状态方程,基于振动系统的时域响应,通过构造一种矩阵迭代算法来反演系统参数。数值算例表明本文方法具有较快的收敛速度和较高的精度。

| Abstract: | This paper is concerned with vibration inversion problems. An iterative method for the system parameter identification is presented. The vibration equation is transformed into state equation, then, a matrix iteration algorithm is constructed for system parameter inversion based on the time domain state response. Numerical results indicate that this method requires only a few iterations to converge to the true solution. |
