摘 要:
通过试验模态分析，实测悬臂对接板的第一阶固有频率及振型，将对接板的动力学问题转化为悬臂对接梁来求解．借助计算机代数语言，编写对接梁的传递矩阵法程序．推导出对接处含角刚度作为符号的方程，输入第一阶固有频率就可识别出该处的角刚度，并通过实例验证了此法的有效性．[著者文摘]

Abstract:
By means of experimental modal analysis for a joint cantilever plate with one end fixed, the first natural frequency and modal shape are determined. The joint plate is treated as a joint cantilever beam. The transfer matrix method is implemented with the computer algebra language. The equation for the angle stiffness is obtained. With the first natural frequency of the joint plate as an input, the angle stiffness can be determined. The validity of this method is shown by experiment.[著者文摘]
