Известные способы градуировки датчиков ускорени , основанные определении среднего значени ускорени на стендах со свободно падающей платформой, сложны и требуют дл своей реализации точной слец-иальной аппаратуры.The known methods for calibrating acceleration sensors, based on determining the mean acceleration value on stands with a free-falling platform, are complex and require accurate deviation equipment for their implementation.
Дл упрощени процесса градуировки предлагаетс способ, ПО которому определ ют высоту свободного падени платформы, врем еарастани ударного импульса и по указанным параметрам и форме кривой ударного «мпулвса суд т об амплитудном значении ускорени .To simplify the calibration process, a method is proposed that determines the height of the free fall of the platform, the time of impact of the shock pulse, and according to the specified parameters and the shape of the impact pulse curve, the amplitude value of the acceleration is judged.
Градуировку датчиков ускорени но описываемому способу производ т следующим образом .The acceleration sensors are calibrated in the following manner.
Известна зависимость, св зывающа форму (уравнение) кривой ударного импульса со средним значением ускорени :There is a known relationship that relates the form (equation) of the shock pulse curve to the mean acceleration:
f(f)di.a.f (f) di.a.
т-врем нарастани ударного импулвса ,t is the rise time of impact impulses,
f(0 - уравнение кривой ударного импульса , f (0 is the equation of the shock pulse curve,
а-среднее з-вачение ускорени в единицах g.a is the average mean acceleration in units of g.
Среднее значение ускорени согласна закону сохранени количества двнн ;енн ири условии замены истинной реакци-н опоры неко-торым средним ее значением можно представить как:The mean value of the acceleration agrees with the law of preservation of the quantity dvn; enn iri provided that the true reaction of the support is replaced by some mean of its value can be represented as:

Так в последнем выражении истиниа реакци заменена некоторой средней реакцией , то при градуировке датчиков нужно учитывать не только среднее значение ускорени , но :и форму кривой ударного импульса.So in the last expression the truth reaction is replaced by some average reaction, then when calibrating the sensors, it is necessary to take into account not only the mean acceleration value, but: and the shape of the shock pulse curve.

Предмет изобретени Subject invention
Сносо:б градуировки датчиков ускорен-и , основанный на олределен-ии среднего SHiaqeН1и ускорени стендах со -свободно падаю щей платформой, отличающийс тем, что, с целью упрощени процесса градуировки, ОЦредел ют .высоту свободного падени платфор мы, врем нарастани ударного -импульса и по указавным параметрам и форме .кривой ударного импульса .суд т об амплитудном значепи-и уско-реп и .Demolition: calibration of sensors accelerated and based on the average of average shiah1 and acceleration of stands with a freely falling platform, characterized in that, to simplify the process of calibration, the free fall height of the platform, the rise time of the shock pulse and according to the indicated parameters and the shape of the shock impulse curve. The trial is about the amplitude value and acceleration rep.
