Abstract
Methods and systems for mitigating vibration in drill strings include performing a drilling operation using a disintegrating tool, obtaining a first load measurement of a first load during the drilling operation using a first load sensor having a first sampling rate in the drill string, obtaining a second load measurement of a second load during the drilling operation using a second load sensor having a second sampling rate in the drill string, wherein the second load measurement is different from the first load measurement, and wherein the first load measurement and the second load measurement are synchronized with an accuracy that is greater than a first sampling interval corresponding to the first sampling rate and a second sampling interval corresponding to the second sampling rate, and performing a vibration mitigation operation
