Документ Features of tire tread wear by rolling(Кропивницький: Центральноукраїнський національний технічний університет, 2023-05-24) Balaka, Maksym; Palamarchuk, Dmytro; Mishchuk, DmytroWear is a more complex process than external friction and is the result of the combined effect of physicochemical and mechanical processes that occur in the surface layer of the tire in contact with the supporting surface of the movement. The prevention task of premature wear and tear of tires is complex and involves the ability to determine their types, as well as unmistakably define the cause of each tire tear. Tire tread wear can occur by different mechanisms depending on the operation conditions: abrasive, fatigue, by rolling. At the same time, the total intensity of wear is determined by the ratio of individual types. Wear indices can change significantly when operating conditions change. Rolling wear is of particular interest, since this mechanism is realized for highly elastic materials and, in principle, cannot be observed in the friction of solid elements or solid rubbers. The wear mechanism by rolling is the highly intensive type. The pneumatic tire turns out to be short-lived if such a wear mechanism is realized.Документ Polymer waste as an alternative fuel source(Харків: ФОП Бровін О. В., 2024-03) Levchuk, Kateryna; Chyrkin, Oleksii; Balaka, MaksymThe problem of polymer waste processing has two aspects: environmental and energy. On the one hand, we improve the environment by destroying polymer waste. On the other hand, this waste is a hydrocarbon derivative and can be a raw material for obtaining alternative motor fuel that will be used in the fuel and energy state complex. The basis of the developed technology, like other similar ones, is low-temperature controlled pyrolysis of polymers without air access in the presence of catalysts. Synthetic liquid fuel can be separated to obtain gasoline, high-quality diesel fuel and heavy fuel oil during the completion of the technological unit with separation and rectification devices.
