用刚度文件FEM，对模型进行不同单元的损伤识别，同时得到损伤程度(The stiffness file FEM is used to identify the damage of different elements of the model, and the damage degree is obtained at the same time.)

自己做的： （一）用双线性变换法设计并用实验系统实现一个三阶的契比雪夫Ⅰ型低通数字滤波器，其采样频率Fs =8KHz，1DB通带边界频率为fp=2KHz。 （二）用双线性变换法设计并用实验系统实现一个三阶的契比雪夫Ⅱ型高通数字滤波器，其采样频率Fs =16KHz，阻带边界频率为fst =4KHz(matlab gui)
