FIELD: measuring equipment.SUBSTANCE: invention relates to measurement equipment, specifically to dynamic calibration of screw dynamometers, used for measuring torque on screw shafts in test hydrodynamic laboratories. Method for dynamic calibration of screw dynamometers involves measurement of torque on shaft screw dynamometer and application of pulse dynamic action to shaft by rupture of flexible connection between pulleys. Simultaneously with measurement of screw dynamometer torque, method includes measuring additional dynamometer rupture force of said flexible connection and measurement results are used to correct sensitivity of converter for converting dynamometer toque into an electric signal depending on value of reference inertia moment of screw dynamometer.EFFECT: technical result is improvement of adjustment of sensitivity of screw dynamometer.1 cl, 2 dwg |
