Abstract
Various embodiments of the present disclosure are directed to methods for operating a test bench with a test object having at least two rotating masses connected by means of a loading shaft to a loading maching for driving or loading the test object. The loading maching controlled by a loading machine control unit. In one embodiment, the method includes: applying loads to the test object on the test bench, estimating an internal test object torque, determining a target loading machine speed, determining a shaft torque acting on the loading shaft, determining acceleration torques for accelerating the at least two rotating masses, addind the shaft torque with the correct sign with the correct sign to the acceleration torques, to form a corrected internal effective test object torque, and determining the target loading machine speed from the corrected internal effective test object torque or a torque derived therefrom.
