Method to test a dynamic torque-generating device and a device to determine the dynamic behavior of a driving shaft

The course of torque transmitted though the driving shaft ( 3 ) between the torque generating device ( 1 ) to be tested and the driving or loading mechanism ( 2 ) is determined during an identification phase in the completely constructed test bench with the use of a rotating driving or loading mechanism ( 2 ) at pseudo-stochastic rotational speeds. Determined are thereby the parameters describing in a real and current manner the dynamic behavior of the driving shaft ( 3 ) whereby said parameters are used as an influence in further testing.
