机械能辅助热扩散渗装置设计与分析
Design and Analysis of a Mechanical Energy-assisted Thermal Diffusion Percolation Device
摘要
Abstract
This paper proposes a novel mechanical energy-assisted nanocrystallization thermal diffusion infiltration method and device,in order to optimize the structure of the thermal diffusion infiltration device.Based on the discrete element method,the motion behavior of the medium balls inside the barrel is simulated.The motion characteristics of the medium balls within the barrel are analyzed using the position density method.The influence laws of liner angle and liner height on the motion state of the medium balls and the position density distribution of the medium balls are studied.The research results indicate that when the liner angle is 20°,the uniformity and concentration of the medium balls in the throwing state are optimal;when the liner height is 24 mm,the dispersion of the medium balls in the throwing area is best,achieving the most favorable throwing state.The research findings provide a theoretical basis for selecting appropriate liner angles and liner heights.关键词
