Main directions of improvement of methods of calculation of loads on carrying and propelling devices of lifting and transport and excavating machines
(Global Science Center LP, 2021) Krupko, I. V.; Yermakova, S. O.; Крупко, І. В.; Єрмакова, С. О.
Thework is a description of the methods of calculating the carrying and propellingelements of hoisting and excavating machines, their design features, methods of calculating the loads on the supporting elements of ma-chines and identified their shortcomings. The description of the developed mathematical model of loading of car-rying and propelling elements with a rigid frame and a rigid suspension bracket of basic elements is given, graphs of loading of basic points at work of cranes, excavators, loaders are presented, conclusions on the basis of the received results are formulated.The mathematical model of loading of carrying and propellingelements of technological machines developed in this work allows to carry out the analysis of loading of carrying points in the course of work at various conditions of support of the car. The developed calculation algorithm allows to trace the influence of various factors on the level of loading of carrying points taking into account the interaction of support elements with the soil.

Теоретичні дослідження стійкості баштового крану з урахуванням розподілу навантажень на опори
(Одеський національний політехнічний університет; Підйомно-транспортна академія наук України, 2020) Єрмакова, С. О.; Іваненко, О. І.; Крупко, І. В.; Ivanenko, O. I.; Krupko, I. H.; Yermakova, S. O.
У статті приведена методика розрахунку навантажень на опорні елементи баштового крана з урахуванням лінійних розмірів машини та просторового характеру дії навантажень. Розроблений алгоритм розрахунку, на основі математичної моделі, дозволяє провести теоретичні дослідження по впливу різних факторів на завантаженість опорних елементів за різними умовами роботи. Для дослідження була розроблена програма в пакеті Maple.
