Wind turbine gearbox simulation data

Abstract

Files containing acceleration signals, representing the vibration response of the modelled gearbox for three full rotations of the shaft. S={5,13} indicates the wind (W) speed considered in the simulation, while X={h,cr} indicates the health condition. 'cr' indicates that the simulation includes the cracked tooth. On the contrary, 'h' indicates that the signal has been produced considering a healthy gearbox and not including damage. Y= {1,2,3} indicates the set of excitation parameters chosen to simulate the signal. The three different excitation parameters (ep) settings used for the experiments can be consulted in Table 4 of the paper. Z={10,13,16} relates to the different crack lengths simulated. Specifically, it indicates the percentage of the dimensionless stiffness function's decrease applied to simulate the tooth crack (tc).
