【摘要】 搅拌筒作为混凝土搅拌运输车的核心部件,其设计的优劣直接决定了整车性能的好坏。本文概述了当前搅拌筒外形尺寸的设计基点以及搅拌筒的核心部件——螺旋叶片的设计方法和计算理论;鉴于当前对搅拌筒的设计都是一种基于经验的优化,而对于搅拌筒工作机理的数值解析尚属空白;因此,本文提出将一种基于离散单元法的固液多相流模型应用于搅拌筒工作机理的解析,从而为搅拌车的设计提供理论性的指导。更多还原

【Abstract】 Mixing tube is the key component of the truck mixer, and its design determines the general performance of the truck. This paper summarize the design theory and method of the mixing tube and its helix vanes; It being the fact that current designs are all based on the experience and the numerical calculations of the truck mixer s tube are still blank at all. Therefore this paper introduces Discrete element method (DEM) attached in a multi-phase flow model to calculate the numerical problem in the mixing tube, and thus provides the theoretical direction to the design of the mixing tube.更多还原
