DEVICE FOR PROGNOSIS OF REMAINING RESOURCE AND PHYSICAL AND MECHANIC MATERIAL PROPERTIES AT NON-DESTRUCTIVE CONTROL

摘要

FIELD: physics, tests.;SUBSTANCE: device is intended for object analysis after natural or artificial magnetic impulse processing. Device includes impact effect source in the form of hammer with built-in Fresnel zonal screen, accelerometer with a pin, personal computer. Concave surface of accelerometer pin has radius=[0.20.3]d, where d is its diameter equal to 4.65.0 mm, so that d/D=1/[4.85.2], where D is diameter of zonal screen of source hammer. Personal computer can perform image analysis of current structural vibration spectre within frequency bands of f_"мс"=17.82550.20 Hz, f_"мр"=81.67956433.89 Hz, f_"сд-о"=1899.662674.25 Hz, during feedback to source, in this case with functioning results effect on functioning character, current and previous digitalised array of fast wavelet conversion in three bands of f_"мс", f_"мр", f_"сд-о" by comparison operand. If results are repeated, comparison operand confirms membrane memory on structure vibrations of the last Langmuir film specifically, and radio emitter signal from built-in PC antenna damps hammer indicator over built-in receiving hammer antenna, and examination finishes. In the opposite case examination continues. Personal computer is intended for prediction of remaining resource T_post-mip after artificial magnetic impulse processing according to indicated formula.;EFFECT: enhanced number of detectable objects.;30 dwg
