Optimization of pneumatic vortex processing for enhanced durability and reliability of machine parts

Abstract

This article addresses the pressing need for advancements in modern mechanical engineering in Uzbekistan, focusing on increasing the durability and reliability of machinery components. The study proposes the utilization of pneumatic vortex processing as an innovative solution, leveraging aerodynamic flow energy, particularly the vortex effect. Through theoretical analysis and experimental studies, various designs of devices for pneumatic vortex processing of cylindrical parts are developed and analyzed. The interaction between deforming balls and the surface being processed is thoroughly investigated, considering factors such as turbulence, surface roughness, and input pressure. Optimal parameters, including ball diameter, number of balls, and inlet pressure, are determined to achieve the desired surface quality. The study reveals the influence of input pressure and initial surface roughness on surface quality and processing force. Findings suggest that by adjusting the diameter and number of balls at a fixed input pressure, optimal combinations can be identified for different workpiece sizes and materials. These results provide valuable insights for enhancing the durability and reliability of machinery components through optimized pneumatic vortex processing techniques.
