Аннотация

В статье приведены результаты моделирования многоточечного контакта при термоэлектрическом методе. Показано влияние разных типов источников термоЭДС на нагрузочную характеристику эквивалентного источника термоЭДС, получаемого за счет параллельного соединения нескольких термопар. Представленная модель реализована в пакете NI LabVIEW, находящаяся в свободном доступе. Верификация модели проведена на трех типах термопар: медь\константан, медь\нихром и хромель\алюмель, с разным их количеством, соединенных параллельно. Полученные расчетные нагрузочные характеристики эквивалентного источника отличаются от экспериментальных не более 6%. Представлены результаты моделирования нагрузочных характеристик эквивалентного источника термоЭДС, получаемого за счет параллельного соединения разного количества двух типов термопар. Показано, что для получения достоверных данных необходимо обеспечить нагрузку эквивалентного источника не менее 1 кОма.
