Исследование процесса буксования колёсной пары рудничного электровоза в переходных режимах

Исследование процесса буксования колёсной пары рудничного электровоза в переходных режимах

Abstract

Описан косвенный метод получения информации об эффекте буксования колесной пары рудничного электровоза на основе использования особой фильтрационной схемы, которая производит фильтрацию измеренного момента сопротивления колесной пары тягового электровоза и выделяет сигнал, величина которого пропорциональна величине буксования. Также в работе представлены результаты имитационного моделирования. Далее выполнен анализ результатов моделирования на основе сравнения графиков линейных скоростей колесной пары тягового рудничного электровоза и корпуса электровоза при использовании алгоритма компенсации эффекта буксования и при его отсутствии. Метод обнаружения эффекта буксования колесной пары и основанный на нем алгоритм управления тяговым электроприводом колесной пары электровоза позволяют повысить энергоэффективность процессов разгона и торможения подвижного состава с тяговым рудничным электровозом.

The paper describes the indirect method of obtaining the information on wheel pair skidding. The method is based on using a special filtration scheme which filters the estimated resistive torque and highlights the signal which is proportional to wheel pair skidding. The work introduces as well the imitation modeling results. The modeling results were analyzed by comparing the linear velocities of wheel pair and electric locomotive in different modes. The method helps to increase energy efficiency of acceleration and braking processes of mobile composition with mine electric locomotive.
