| 摘 要： | 通过实测交叉梁系低阶的固有频率,以传递矩阵法为基础,由计算机代数语言推导出含待识别支承刚度的高次方程或非线性方程组,解此方程就能识别出支承刚度,并通过实验来验证该方法的有效性.

| Abstract: | By means of measuring the lower natural frequencies of cross beams together with transfer matrix method, the high-order equation or nonlinear equation sets can be deduced by computer algebra language. This equation contains unknown quantity of the supporting stiffness. Thus the stiffness can be identified. The effectiveness of this method has been proved by experiments. |
