DEVICE FOR MEASURING PARAMETERS OF IMPACT IMPULSE Russian patent published in 2004 - IPC

FIELD: measuring equipment.

SUBSTANCE: device has three one-component piezoaccelerometers(or single three-component one), sensitivity axes of which are mutually orthogonal, three amplifiers of electrical charge, current amplifier, supporting voltage source, eight-digit high-speed analog-digital converter, memory block, generator, control device, autonomous one-pole power source, power voltage converter, voltage switch. Outputs of piezoaccelerometers are connected to respective first inputs of charge amplifiers, second inputs of which are connected to output of current amplifier, input of which is connected to output of support voltage source and to fourth input of analog-digital converter, first, second and third inputs of which are connected to outputs of respective charge amplifiers. Output of power source is connected to first inputs of power voltage converter and power voltage switch, second input of which is connected to control device output, first input of which is connected to generator output. Voltage switch output is connected to first input of memory block, second input of which is connected to output of analog-digital converter and to second input of control device.

EFFECT: possible measurement of all parameters of impact impulse (length, amplitude, growth speed and fade speed, spectrum and so on) along three orthogonal axes directly in area of impact effect.
