“…During the experiments the CB breakdown did not occur. A scheme of full three-factor experiment with two levels without repetitions, including the interactions, was created, whereas the number of all possible experimental runs was again 2 3 , i.e., 8 experimental runs. Graphical representation of the experiment using a cube is shown in figure 2, where the cube corners contain the response values.…”

“…Large-scale continuous material transport (belt conveyor system) is encouraged to move large volume rapidly and due to high efficiency of continuous transportation compared with the discrete transport (by trains or trucks) [1,2]. Conveyor belts (CBs) are used in practically every industry where large quantities of goods are moved [3]; they are widely used to transport granular matter in bulk [4]. The CB transport systems have taken on a new significance in recent years.…”

“…CBs can be loaded with hundreds of tons of goods every hour, depending on the application, which causes elastic, as well as plastic, deformation of the material and, over time, wear. Impact loading is an important process in the transport industry as it causes wear and failure of critical components [3]. In the beginning the belt damages are not visible on their external surface.…”

This work deals with establishing the tension load by impact dynamic testing of rubber composite conveyor belts. The value of tension load affects the shape of the used impactor and use of a support system as well as the weight of the ram and the impact height. An increase in the allowable stress when the belt is tensioned was examined during the test, to determine the effect of impact on the tension load. The obtained values of tension load are assessed using basic mathematical and statistical methods. Using the Design of Experiments method, factors that significantly affect the value of the tension load are identified.

“…These studies have mainly focused on the resistance of a belt while running. The resistance between the belt and the rollers accounts for approximately 60% of the total resistance during belt operation [ 5 , 7 , 14 , 15 ]. The elastic modulus of the bottom cover of the belt is also an important factor for running resistance.…”

The implementation of multiple drives for belt conveyors can solve the problems associated with motor overpower and the excessive tension of conveyor belts powered by a single drive. However, multiple drives can suffer from uneven driving power allocation. Among various factors, the selection of the type of conveyor belt particularly affects the power allocation. The current study aims to investigate the influence of the elastic modulus of a conveyor belt on the power allocation of multi-drive conveyors. Based on the Kelvin-Voigt viscoelastic model, a discrete model of an entire machine is established. Kelvin-Voigt software is used to simulate the working conditions of conveyor belts with different elastic moduli under full loads. The driving forces of individual rollers are obtained and then compared. Compared to other types of belts, a steel wire core conveyor belt, whose elastic modulus is relatively high, effectively improves the stability of the conveyor belt under a full load after start-up to achieve a reasonable power allocation. The results of this study provide a foundation for conveyor belt selection for multi-drive conveyors.

Енергопоглинаюча здатнiсть може бути використана для вимiрювання опору матерiалу балiстичному удару. Метою даної роботи є аналiз енергопоглинаючої пластини з гумовим покриттям за допомогою пострiлу деформованими снарядами. Дане дослiдження проведено з використанням чисельного моделювання на основi кiнцевого елемента, пiдтвердженого експериментальними результатами. Установка моделювання на сталевiй пластинi з рiзною твердiстю з додаванням товщини гуми виготовлена у виглядi балiстичної випробувальної панелi. Шари не були закрiпленi на заднiй пластинi. Пострiл в панель здiйснювався з використанням деформованої кулi калiбру 5,56×45 мм з вiдстанню 15 м вiд нормального кута атаки. Для моделювання використовувався алгоритм по методу кiнцевих елементiв з моделями еластопластичного матерiалу Джонсона-Кука i Мунi-Рiвлiн. Результати моделювання показують, що енергiя балiстичного удару, отримана i поглинена панеллю, значно зростає незабаром пiсля зiткнення до тих пiр, поки не досягне певного значення на однiй пластинi, де енергiя зменшиться завдяки успiшному проникненню снаряда в пластину. У той час як на шаруватiй пластинi, пiсля того, як снаряду вдалося проникнути в передню бiчну пластину, енергiя поглинання досягла максимального значення i не змiнилася, що призвело до того, що снаряд не змiг проникнути в наступний шар. Данi результати свiдчать про те, що додавання гуми з шаруватою структурою дозволяє поглинати енергiю балiстичного удару. Ключовi слова: поглинач енергiї, тверда пластина, м'яка пластина, балiстична шарувата пластина, гума, балiстичний удар, моделювання
