摘要
The device for measuring the parameters of thrust impulses has an acceleration source, which converts mechanical oscillations of a test object into electrical signals, connected via an amplifier stage to means for measuring the impact velocity. The means (3) for measuring variations in the impact velocity comprise an integrator (4) connected to the output of the amplifier stage (2), together with a mill stage (5) with a separate supply source (6) connected to its other input. The mill stage (5) is connected to a switch (8) coupled to the second input of the integrator (4). Two triggers (12, 13) are connected to two further integrator inputs directly and via a second switch (15) also having a separate supply source (17). A second mill stage (19) is connected to the output of the integrator (4) and coupled via. a pulse former (21) to a impact velocity variation display (23).
