Рассмотрен вопрос об альтернативной форме токосъемных элементов. Изменение традиционной формы анализируется с точки зрения повышения износостойкости и надежности скользящих электрических контактов токосъемного узла. В работе показано влияние формы токосъемных элементов на углеродной основе на аэродинамические и трибологические характеристики. На основе полученных данных разработана альтернативная форма, позволяющая снизить интенсивность изнашивания и увеличить стабильность токосъемного узла. Показано, что аэродинамическая форма токосъемных элементов позволяет уменьшить их повреждаемость и интенсифицировать их охлаждение. В работе использован подход, основанный на неравновесной термодинамике и теории самоорганизации.

The aspect under discussion is alternate shape of current collection elements. Modification of their traditional shape is tackled from the viewpoint of achieving better wear resistance and reliability of the current-collector unit’s sliding contact strips. There is indicated influence exerted by the shape of the collection elements on the aerodynamic and tribological performance. Based on the obtained data there was developed alternate collection element shape version contributing to lesser wear intensity and better stability of the collector unit. There is also indicated that aerodynamics-friendly shape of current collection elements contributes to their lesser damageability and more intensive cooling. The approach to the problem under discussion taken by the authors bases upon non-equilibrium thermodynamics and self-organization theory.
