Problem. The analysis of the ripper working elements designs showed that their improvement perspective direction is using vibration and impact actuating elements. They work by the principle of dynamic energy accumulation with its subsequent use. However, there are currently no approaches to determining the tip rational parameters with the dynamic cutting edge. Goal. The main hypothesis formation and justification of the superposition principle impact on the working environment of actuating elements for ripper-pick. Methodology. Analytical methods of studying the soil destruction process by site preparation machines equipped tip with a dynamic cutting edge were used. Results. The presented model that describes the soil destruction process by the tip with the dynamic cutting edge has been developed. It combines the work of static force, determined by the traction parameters of the base machine, and the work of dynamic forces, determined by the physical and mechanical conditions of the soil destruction process. As a result, we obtained an equation for determining the force to overcome soil cutting resistance by the tip with the dynamic cutting edge. Originality. We propose to apply the superposition principle of effecting several factors on the working environment simultaneously in the soil destruction process by ripper-pick, such as static and dynamic load, due to the possibility of energy accumulation with subsequent use. This would create the high-speed power pulse on the cutting edge to ensure the preliminary formation of the compressed zone in the massif, with decreases in the power intensity of the static load for complete separation of the soil element. Practical value. The presented hypothesis will allow the technological basis development of such systems creation and application to develop fundamentally new technical solutions, to create effective, safe and durable working elements.
