This is a program to study the dynamic instability of cylindrical shell due to parametric excitation.

说明：  用S变换对电压暂降进行检测，得到基频幅值，相位跳变，突变点，谐波检测，频率幅值包络线等特征量(The S-transform is used to detect the voltage sag, and the characteristic parameters such as fundamental frequency amplitude, phase jump, mutation point, harmonic detection, frequency amplitude envelope are obtained)
