Substantiation of the process of vertical transportation of piece loads / Petro Koruniak, Iryna Nishchenko, Volodymyr Borovets // Ukrainian Journal Of Mechanical Engineering Andmaterials Science. — Lviv : Lviv Politechnic Publishing House, 2017. — Vol 3. — No 1. — P. 81–88.2411-8001https://ena.lpnu.ua/handle/ntb/39555The urgent problem of automatization of the process of products transportation with a help of vertical chutes under the influence of gravitational forces using elastic elements is considered. The interaction between the object being transported and the elastic elements is defined. Their mutual influence on the transportation speed is determined depending on the contact parameters. The analysis of the object transportation speed changing depending on friction and on the zone of their mutual contact is carried out.81-88envertical chuteelastic elementsmall ballbeamArticle© Національний університет "Львівська політехніка"© Koruniak P., Nishchenko I., Borovets V., 20178
