Abstract
The control arrangement enables, with the aid of a start-up control device which is connected with an oscillation or vibration pickup or transducer which is affixed to the generating cylinder of the machine, running-up of the measuring drive at an optimum acceleration to the final or end measuring velocity, so that already at the start of the measuring operation there are obtained valid measurement results, in other words measurment results which are not impaired by the natural oscillations or vibrations of the machine, without there having to be relinquished at the machine the advantageous presence of a lever system and generating straight edge, and thus, the positive motion transmission between the slide system and the test gear. The optimum acceleration, i.e., the slope or ascent of the start-up curve of the measuring drive is determined by the start-up control device as the product of the reciprocal value of the set torque or rotational moment of an auxiliary drive motor and the reciprocal value of the envelope amplitude of the vibration signal delivered by the oscillation or vibration pickup.
