Abstract
Systems and methods for mitigating vibration in downhole strings are described. The methods include obtaining first and second load measurements of first and second loads during a drilling operation and creating first and second load measurement data, with first and second load sensors separated by a sensor distance. First and/or second representative values of the first and second loads are determined form the first and second load measurement data and the sensor distance. The determined representative value(s) are compared against respective load limit(s) and a vibration mitigation operation is performed in response to the determined representative value(s) equaling or exceeding the respective load limit.
