Description
. 1. one
Изобретение относитс к области автоматики и измерительной техники и предназначено дл использовани преимущественно в системах дл прочностных усталостных испытаний авиационных конструкций. Оно может быть использовано также в различных об- . ласт х экспериментальной техники, где испытываемый объект подвергаетс циклическому воздействию по какому- ю либо механическому параметру Ссила, давление, деформаци , перемещение, скорость, ускорение и т,д.) по заданной программе испытаний.The invention relates to the field of automation and measurement technology and is intended for use primarily in systems for strength fatigue testing of aircraft structures. It can be used also in various ob-. areas of experimental technology, where the test object is subjected to cyclic impact on any or mechanical parameter Force, pressure, deformation, displacement, speed, acceleration, and so on) according to a given test program.
Известно устройство дл управле- is ни циклическим нагружением при прочностных испытани х 1.A device for controlling is not cyclical loading in the strength tests 1.
Недостатком этого устройстве вл етс зависимость точности воспроизведени фактических экстремальных 20 значений параметра нагруженй от динамических характеристик следующей системы, что снижает его точность и надежность.The disadvantage of this device is the dependence of the accuracy of reproduction of the actual extreme 20 values of the load parameter on the dynamic characteristics of the next system, which reduces its accuracy and reliability.
Наиболее близким к предлагаемому по техническому решению вл етс устройство дл управлени циклическим нагружением при прочностных испытани х , содержащее программный задатчик, датчик нагрузки, подключенный к входу устройства, и включенные последовательно интерпол тор и след щий исполнительный блок, соединенный с выходом устройства fij.Closest to the proposed technical solution is a device for controlling cyclic loading during strength testing, which contains a software setpoint, a load sensor connected to the input of the device, and an interpolator connected in series and a tracking actuator connected to the output of device fij.
Недостатком такого устройства вл етс невысока точность, обусловленна зависимостью экстремальных значений воспроизводимого параметра нагруженй , например силы от динамических характеристик след щей системы .The disadvantage of such a device is low accuracy, due to the dependence of the extreme values of the reproduced load parameter, for example, force, on the dynamic characteristics of the tracking system.
