Dataset for the CCTFA Method

The dataset consists of simulation data and vibration data collected from rotating machinery using the Donghua testing system. It is specifically designed for performance testing of the CCTFA method.The simulation data, generated by running a Matlab program, is saved in .m file format. This data includes the performance of the CCTFA method regarding window width, signal amplitude fluctuation, signal frequency change rate, signal quality, and comparative results with other methods. The real experimental data comprises two parts: a sine wave signal with a fluctuation range of 1 Hz and a triangular wave signal with a fluctuation range of 20 Hz. All real experimental signals were collected using an eddy current sensor (Type: 5E101-2, Dong Hua Test, China) in the Donghua testing system.
