ABSTRACT:
An impact impulse measuring device comprises an acceleration transducer which converts the mechanical oscillations of the object being tested into electric signals which are applied to an amplifier unit which is electrically coupled to a means for measuring the parameters of an impact impulse via a means for automatically switching the range of measuring impact impulse parameters. The means for measuring parameters of an impact impulse includes a comparator connected to one of the inputs of a digital-analog converter and a reference voltage source connected to another input of the digital-analog converter, the digital-analog converter having its third input connected to a high-frequency pulse generator. A first input of the means for automatically switching the range of measuring parameters of an impact impulse is connected to an output of the amplifier unit, a second input is connected to an output of the high-frequency pulse generator, a third input is connected to an output of the reference voltage source, a first output is connected to the comparator, and its second output is connected to a reset bus of the digital-analog converter.
