Increasing the operational reliability of agricultural machinery components operating under conditions of intensive abrasive wear is a priority task of modern mechanical engineering. Surface plastic deformation using hydropulse devices is an effective method of forming a hardened layer, however, the stability of this process is significantly limited by the degradation of the geometric shape of the working tool.
The article analyzes the dynamics of the interaction of impact tips of various configurations (sphere, cone, trapezoid) with the treated surface. The evolution of the tool shape change under conditions of high-frequency cyclic loading and its influence on the energy parameters of the impact are considered. The study is based on the method of mathematical modeling of viscoelastic systems based on the Kelvin-Voigt model, which allows describing the hydropulse drive as a parametric system with a built-in pressure pulse generator.
In the course of the work, mathematical dependencies were determined for estimating the force of impact interaction, which took into account the elastic-plastic response of the part and the involutely small deformation of the tip. The kinematic characteristics of the piston-striker were calculated, in particular the maximum speed at the moment of contact and the rebound parameters. The use of the “elastic-concentrated model” of the energy carrier was justified to minimize the dimensions of the device while maintaining a high pulse frequency (up to 100 Hz). It was established that the use of the refined mathematical model allows adapting the processing modes to increase the wear resistance of agricultural machinery parts by 1.5–2 times.
The proposed approach, combining a refined mathematical model with adaptive control of the energy and geometric parameters of hydropulse loading, ensures the predictable formation of a hardened surface layer with enhanced wear resistance and stable properties over a wide range of operating conditions.
