FIELD: test methods.
SUBSTANCE: method is based upon shock loading of tested object. Shock is created by means of special pyrotechnic devices with predetermined shock spectrum of accelerations, which cover over required shock spectrum of accelerations. Then distance from pyrotechnic devices to tested object is measured at which distance registered shock spectrum of acceleration is narrower than required one. Number of points of application off shock is determined afterwards and shock is created in those points. Achieved shock spectra of accelerations in all the inspection points are compared with required shock spectrum of accelerations and number of pyrotechnic devices and areas of their installation are corrected if needed. Procedure is repeated until required shock spectrum of accelerations is provided in all the inspection points.
EFFECT: improved precision of reproduction of signal: improved quality of testing.
