Analysis of dynamic processes in the impact system of drilling machines

Abstract

Modern drilling machines designed for the destruction of rocks have a diverse structure, various performance characteristics and in most cases a well-defined limited scope of application. The most common for the destruction of rocks of high strength are impact drilling machines. One of the most effective ways to increase the productivity of such machines is to find rational geometric parameters of colliding elements. The article proposes and substantiates a methodology for studying shock systems based on the application of the shock wave theory. According to the calculation results, the parameters and design solutions of the elements of drilling machines are given, the use of which will allow to increase productivity and reduce energy consumption for the destruction of rock.
