Study on the Simulation and Variation Law of Particle Erosion Velocity of Flow Field in Recoil Mechanism

Abstract

During the recoil and recoil motion of the gun, the solid particles in the recoil mechanism will repeatedly impact the control ring, resulting in erosion and wear phenomenon, which has become the main cause of the failure of the control ring. By means of fluent software, a two-phase flow model based on liquid-solid coupling is established, and the motion trajectory and erosion velocity of solid particles are calculated by numerical simulation, and the influence of different parameters on particle erosion velocity is studied, which provides reference data for the simulation of controlled ring erosion and the study of wear law.
