摘要
以传递矩阵法为基础,用计算机代数系统编程,导出以联接刚度为未知量的方程,输入杆件纵向振动的第二阶固有频率,从而识别出杆件的联接刚度,并通过实验来验证该法的正确性。
By means of the transfer matrix method and a program of the computer algebraic system, the paper obtains the equation with the joint stiffness as the unknown. With the second natural frequency of the beams, the joint stiffness can be identified. The validity of this method has been proved by experiment.
