    Розроблено математичну модель вертикального стрічкового ківшового елеватора, в якій тяговий орган (стрічка) представлено як пружний елемент з одностороннім зв’язком, що працює на розтяг, через кусочні функції зміни реакцій у цьому ж елементі.The mathematical model of the vertical belt bucket elevator has been developed. In this model the pulling element is presented by piecewise function as an elastic element with one-side constraint and works in tension

    Dynamic stresses, which arise in drive and traction element during operation of the conveyor have been investigated on the basis of the developed mathematical model. Calculation has been conducted with regard to its elastic and dissipative properties. The analysis of the obtained results has been carried out, with and without taking into consideration dissipative properties of the conveyor's element

    The way of reducing oscillations of the belt bucket elevators elements, during the transients, has been resulted by optimizing the start-up mode of the drive mechanism for the kinematic criteria. On calculation the resistance forces at scooping the material have also been taken into consideration
