Rotor vibration dataset

This dataset contains time-domain and frequency-domain vibration signal produced by simulation model of a large flexible rotor (a tube roll, typically used in paper machines). Simulation runs are conducted for 9 seconds with a sampling rate of 2000 Hz. It contains 52266 samples, in which the speed is varied from 4 Hz to 18 Hz, and the horizontal foundation stiffness is varied between 2.04 MN/m and 18.32 MN/m. Each sample represents the horizontal or vertical center-point movement in the specified location of the rotor. In frequency- domain response signal amplitudes are up to 25 Hz , as the critical speed varies from 9 Hz to 21 Hz.
