The paper justifies the importance of the experimental determination of rotational variability of cardan drives and couplings.
The objective of the authors’ team was to elaborate a new automated test machine for the determination of this variability. The principle design of this new automated test machine is described in details. The advantages of the application of electronic measuring equipment in combination with PC for the automation of the measuring and experimental data processing are pointed out. The test machine gives opportunities for changing of the angles between the driving and the driven shaft and for regulating the rotational speed of the driving shaft.
The other functions of the electromechanical test machine are described in details in the paper. Conclusions are made: the methodology for experimental research of rotational variability of cardan drives is improved; the application of electronic test machine verifies the advantages of the usage of high sensitive and precise sensors of new generation; contemporary approaches are applied.
