Abstract: The course of torque transmitted though a driving shaft (3) between torque generating device (1) to be tested and a 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 parameters describing in a real and current manner the dynamic behavior of the driving shaft (3) whereby the parameters are used as an influence in further testing.
