Abstract
Modern rotary-impact mechanisms for the destruction of solid and frozen soils have a bulky and complex design. The development of a method for improving the rotary-impact mechanism construction allows solving the problem of reducing the energy intensity of the soil destruction process. The algorithm of the geometrical parameters determination of the rotary-impact mechanism is scientifically substantiated on the basis of the modern technical solutions' analysis of drilling rigs and physical bases of the drilling tool interaction with the soils of various difficulty categories. An analytical method with the use of modern computer technology, fundamental provisions of theoretical mechanics and strength theory are applied in theoretical and experimental research. The scientific innovation of the research involves a theoretically and experimentally verified method of basic engineering parameters selection for a fundamentally new rotary-impact mechanism (patent No. 2232858 of the Russian Federation) depending on the drill bit types. The proposed method for evaluating the resistance features of structural elements allows determining the P value of the non-destruction force to provide a safe impact on the groove base during drilling tool operations.
