THE CALCULATION OF THE PREFORMATION PARAMETERS ON THE BASIS OF MODELING IN THE SOFTWARE COMPLEX DEFORM 3DAbstract. The calculation methodology of preformation parameters with the use of the software complex DEFORM 3D is presented. It makes it possible to take into account both the wire form and its mechanical properties.Keywords: rope, preformation, model, software complex, accumulated deformation and shearing strain, stress-strain state, the tuning of preformation.В процессе свивки каната его элементы испытывают упругопластические деформации изгиба, растяжения и кручения, за счет которых в проволоках возникают нормальные и касательные напряжения. Напряжения, остающиеся в канате после свивки, снижают прочност-ные свойства, выносливость, износостойкость прово-лок, тем самым уменьшают работоспособность каната. Для нейтрализации или перераспределения остаточных напряжений в проволоках каната применяются различ-ные методы механической обработки. Одним из них является преформация, сущность которой заключается в придании проволокам той формы, которую они при-обретают при свивке [1, 2]. Применяемые в настоящее время методики определения параметров преформации носят эмпирический характер и не учитывают форму и свойства проволоки, а также реальное деформирован-ное состояние проволок в момент преформации.В настоящее время известно применение метода конечных элементов (МКЭ) при исследовании напря-женно-деформированного состояния каната при его эксплуатации [3, 4]. Однако, работ, посвященных рас-чету параметров преформации с применением МКЭ, не обнаружено.В настоящей работе предложена методика расчета параметров преформации с применением программно-го комплекса DEFORM 3D. Методика включает в себя модель реального процесса преформации проволоки при свивке каната с учетом механических свойств и формы, анализ результатов моделирования и выдачу рекомендаций по настройке преформатора. Модель позволяет оценить влияние варьируемых параметров (угла отклонения центральной оси среднего ролика от-носительно крайних роликов (угола α преформации), диаметра роликов, расстояния между крайними роли-ками) преформации на степень накопленной и сдвиго-вой деформаций, характер распределения деформаций по длине и сечению проволоки, степень и характер рас-пределения напряжений, силовые параметры.В качестве примера в программном комплексе DEFORM 3D смоделирован процесс преформации проволок при свивке каната диам. 6,2 мм конструкции 1 + 6 (диаметр центральной проволоки равен 2,1 мм; диаметр проволок повива -2,05 мм) по ГОСТ 13840, угол свивки составляет 19°, ша...

Drilling wells is one of the primary methods used for mineral exploration. Scientific studies have aimed at improving the technical and economic aspects of drilling because of the current competitive economic conditions. Note that the primary topic of these studies has been developing new effective rock-cutting tools. To design a new rock-cutting tool, a thorough, reliable, and accurate study of the processes that occur during drilling is necessary. During drilling, mechanical, hydraulic, thermal, and chemical phenomena, which are interdependent and affect the performance of a drilling tool, simultaneously occur; therefore, a systematic, integrated approach is required for studying drilling processes. Field-based and laboratory experiments are quite tedious to perform and require high material costs, and it is often not possible to separately evaluate small elements of the drilling model. Therefore, computer simulation is an important research tool that enables accurate and reliable visualization of even small parts of the model. The aim. The aim of this study is to examine the potential for computer simulation of the processes that occur during drilling. Objective. In this study, we evaluated the simulation features of various software products, such as KOMPAS-3D, ANSYS, Delphi, and LabVIEW, for their utility in studying the processes that occur during drilling. The possibility of computer simulation for studying drilling processes, including its advantages and disadvantages, are demonstrated. The results are obtained from a model that simulates a rock cutting tool. The main uses of the rock cutting tool are outlined, and the drilling simulation development is planned. Choice of research method. The study of the capabilities of existing modern software products, for use in drilling process research, is carried out by an analytical review method.
