Mathematical model of the belt bucket elevator’s movement dynamics with one-side constraint of the pulling element
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

Ematical model of the bucket elevator's movement dynamics
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 conveyor start-up mode optimization by a dynamic criterion tacking into consideration resistance forces
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
