Description
Изобретение относитс к аналоговым вычислительным машинам, а именно к аналоговым вычислительным устройствам Д;1 моделировани потоков жидкости или газа и может быть использовано.при рас чете переходных процессов в водопровод- ных и других системах, динамические свойства которых определ ютс ураввеви ми длинной линии с малыми тепловыми и механическими потер ми. Известны устройства дл моделировани переходных процессов в трубах. Состо щие .из пассивных фильтров нижних частот Ij. Однако они позвол ют моделировать процессы в газовых трубах со значительными погрешност ми. Наиболее близким к предлагаемому вл етс устройство дл моделировани аэродинамических процессов в шахтах, содержащее фильтр нижних частот 2. Недостаток устройства состоит в том что его применение не позвол ет при расчетах сложных систем трубопроводов получать решение с достаточной точностью. Цель изобретени -повышение точности моделировани . Поставленна цель достигаетс тем, что в устройство дл моделировани волHOBbix процессов в трубопроводных системах , содержащее два последовательно соединенных дроссел , общий вывод которых подключен к первой обкладке положительного конденсатора, втора обкладка которого соединена шиной нулевого потенциала , свободный вывод первого дроссел вл етс входом устройства, свободный вывод второго дроссел соединен с одним выводом разв зывающего резистора, другой вывод которого Ьоединен с шиной нулевого потенциала, введен решающий усилитель , свободный вывод второго дроссел подключен к входу решающего усилител , выход которого вл етс выходом устройства. На чертеже представле«а схема устройства .The invention relates to analog computing machines, namely, analog computing devices D; 1 to simulate liquid or gas flows and can be used when calculating transients in plumbing and other systems whose dynamic properties are determined by an equation of long line with small thermal and mechanical losses. Devices are known for modeling transients in pipes. Consisting of passive low-pass filters Ij. However, they make it possible to simulate processes in gas pipes with significant errors. The closest to the present invention is a device for modeling aerodynamic processes in mines, which contains a low-pass filter 2. The drawback of the device is that its use does not allow a solution with sufficient accuracy to be used in calculations of complex piping systems. The purpose of the invention is to improve the accuracy of modeling. The goal is achieved by the fact that in a device for modeling HOBBix processes in pipeline systems containing two series-connected droplets, the common output of which is connected to the first plate of a positive capacitor, the second plate of which is connected by a zero potential bus, the free output of the first switch is a device input The pin of the second choke is connected to one pin of the isolating resistor, the other pin of which is connected to the zero potential bus, a decisive gain is introduced An optional free output of the second throttle is connected to the input of the decision amplifier, the output of which is the output of the device. The drawing shows a device diagram.
