| 摘 要： | 提出了一种逆优化系统识别动态载荷的方法。该方法避免了一般载荷识别中频响函数求逆运算中由于矩阵病态而引起的运算及运算失败，从而提高了识别精度，为动态载荷，特别是宽频带、瞬态冲击载荷的识别提供了一种有效途径。

| Abstract: | A method using inverse optimizing system analysis to identify a dynamic load is presented, which can reduce arithmetic errors and avoid arithmetic failure produced by the ill condition of the FRF matrix in inverse operation of the matrix. Thus, the precision of identification can be raised. This method provides an efficient way for dynamic load identification, especially for impact load which has the wide frequency bandwidth. |
