Noncontacting torquemeters calibration is one of the acute tasks currently. Such sensors are widely used in measuring torques and torsional oscillations of elastic shafts of industrial plants and electromechanical systems. Noncontacting torquemeters must be properly calibrated before they are used to measure torque and torsional oscillations of rotating shafts. The paper describes a new approach to solving the task of calibration of noncontacting torquemeters and torsional oscillations meters of elastic shafts. The approach is based on the finite elements method as well as realized in the measuring device-torquemeter. The torquemeter allows to measure little torques and torsional oscillations of elastic shafts of electromechanical complexes.

This article considered method to measure low-frequency angular oscillations of rotors of electric machines and solved the problem of assess shear deformations of rotating shafts in transient conditions. Method of calculating torsional torques is considered by the example of electric generator shaft of diesel generator unit. This method allows taking into account the angular deformations of the rotating shafts, and reducing vibration overloads, and increasing in both resource and reliability.
