Automation of design for dynamic loading at the designing stage of mining machinery

Abstract

Meeting the growing needs of the state’s economy for the raw materials needed for the production of ferrous and non-ferrous metals accelerates the technical re-equipment of the mining industry through the introduction of new, more powerful equipment. This circumstance determines the urgency in the automation of calculations at the design stage of mining machines. The originality of the developed software product is in consideration of the actual loads acting in the working equipment of a career excavator. Actual dynamic loads significantly exceed their calculated values, which leads to an increased number of structural element failures. At the design stage, with the use of the developed program, it is possible to establish rational cross-sectional dimensions of the handle metalwork taking into account the actual loads arising during the rock mass excavation and stress concentrators.

Features of the tripping mechanization with the horizontal pipe laying

“…The issues of the mechanization influence on the efficiency of technological processes were considered in the papers [1][2][3]. They show the relevance and areas of the equipment improvement [4][5][6], but do not reflect the full range of the systematic approach application for selection of the drilling equipment designs for the specific operating conditions.…”
