This study investigates the dynamic interaction between an elastically deformed working body of a ripper-pick and soil. The focus is on enhancing labor productivity in earthmoving operations by understanding and leveraging the energy accumulation and release mechanisms in soil cutting processes. A theoretical framework is developed based on the kinetic energy theorem, which describes the energy balance within the “elastically deformed executive element (EDEE) of the ripper-pick-soil” system. The research derives an expression for the force required to overcome soil resistance, incorporating factors such as cutting depth, tip width, console length, and soil properties. Analytical results demonstrate that soil resistance to cutting increases proportionally with cutting depth and parabolically with tip width, while decreasing rapidly with changes in console thickness. The study identifies optimal geometrical parameters for EDEE tips, highlighting that effective soil cutting is achieved when the EDEE length is half the tip width and the console thickness is close to 10% of the tip width. These findings offer the recommendations for designing efficient, safe, and durable working bodies for ripper-picks, providing significant implications for improving the productivity and efficiency of earthmoving machinery.
