Sorry for the delayed response.

We have checked the details. The sampling frequency is set as 8192 data points per mininute. I hope it will be helpful.

Dear Dr. Liu.
I'm very sorry to bother you again. As I read your two papers on fault diagnosis of this dataset, you mentioned that the original data was downsampled by 1/8. I would like to confirm with you again, is the sampling frequency in these table files 8192 points per minute? Because a sampling frequency of 136.53Hz seems too low. Or is it 8192 points per second? Thank you for your patience in replying.

Dear Junqing,

Thank you for your careful reading of our papers. To clarify, the sampling frequency is indeed 8192 points per minute, which was the original sampling setting used during data collection by the engineers, and the table files contain the data as directly saved during that process.

If your application requires a different sampling frequency, you may find our recently released open-source dataset helpful. It can be accessed here: MCC5-THU Gearbox Benchmark Datasets. This dataset includes cases of compound faults and may better suit your needs, depending on your specific requirements.

Best regards,
Zeyi
