Simulation Study on Erosion Wear Rule of Aluminium Brass Throttling Ring of Artillery Based on Finite Element Method

摘要

s. Erosion wear is the main failure cause of the throttling ring in artillery, which will lead to the reduction of the reliability of the throttling ring, which also will lead to degradation of the performance of recoil brake. According to the working conditions and environmental characteristics of the throttling ring, the finite element model of the erosion wear of the throttling ring is established, and the erosion wear simulation test is carried out to study the erosion wear rules of the throttling ring under different influencing factors, so as to evaluate the reliability of the throttling ring reasonably. It is of great theoretical and practical value to obtain the reliability information of the throttling ring under different working conditions and to ensure the normal performance of the recoil brake.
