Аннотация (краткое описание)
In this study is presented an analytical mathematical model developed to determine the forces arising during the active penetration of machine working bodies into sticky rocks. The methodology is based on the method of element-by-element calculation of resistances, where the contact zone is divided into discrete prisms of material. As a result of the analysis, a final formula for the total penetration force is derived. This formula shows the dependence of the resistance force on the dimensions of the tool (thickness, depth, angle of sharpening) and the physical characteristics of the rock (internal friction, adhesion, stickiness). The model serves as a reliable engineering tool for the design and optimization of working bodies of earthmoving and mining equipmentDOI

In this paper is presented and described in detail a mathematical model of active interaction between the working body and an array of sticky rock during normal penetration. Based on the method of element-by-element calculation of resistances and a number of physically justified assumptions, a final analytical formula for calculating the penetration force is derived. Key findings: 1. The developed model allows quantitative determination of resistance force as a function of the geometric parameters of the tool (thickness, width, sharpening angle) and the physical and mechanical properties of the rock (weight, friction, adhesion); 2. The formula clearly divides the total resistance into components determined by the weight of the rock, its internal strength (cohesion), and adhesive forces (adhesion), which allows for analysis of the energy expenditure structure; 3. The model analytically confirms the practical importance of optimizing the geometry of the working body, in particular, it shows the effectiveness of reducing the thickness and sharpening angle of the cutting edge to reduce the energy intensity of the cutting process. The presented model is a ready-made engineering tool that can be used in the design of working parts for bulldozers, scrapers, excavators, and other equipment to increase their efficiency when working in difficult conditions with sticky and hard rocks. It provides a theoretical basis for making informed design decisions aimed at reducing energy consumption and increasing machine productivityКвартиль
