3D Printing Injection Theory and Simulation Analysis of PBX Explosive
摘要
Abstract
To solve the problems in conventional shaping of PBX explosive, such as long time consumption, complex process, many control factors, and difficult forming of special-shapes, a novel 3D printing injection molding method is proposed based on the theory of 3D printing injection. The material to be formed is injected onto the substrate by the high precision injection mechanism, stacking point by point until a three-dimensional shape is obtained. In this paper, a theoretical model of single droplet contacting with substrate and droplet accumulation is established, and the factors influencing the surface roughness of the formed explosive are defined. These main factors, such as the nozzle diameter the striker stroke and the driving pressure, influencing the injection are found by simulation analysis using the software Fluent. In addition, orthogonal experiments are designed to determine the relationship among the factors, hence the sim-ulation results are proved to be consistent with the theoretical analysis. This study may provide theoretical and method-ological supports for integrated shaping of PBX explosive.关键词
