基于EDEM的混凝土物料搅拌分析
Analysis of Concrete Material Mixing Based on EDEM
摘要: 建立了水凝混凝土立式搅拌机三维模型，在EDEM软件中对其材料参数、接触参数、全局变量、运动参数以及求解器等进行设置。通过离散元仿真对混凝土物料的运动特性、搅拌均匀度进行了分析。正交实验得出搅拌机搅拌参数最佳组合为铲板安装角45˚、搅拌速度35 rpm、充盈率0.4时，混凝土的搅拌效果最好，为立式搅拌机的设计生产提供了参考。
Abstract: The three-dimensional model of the hydraulic concrete vertical mixer was established, and its material parameters, contact parameters, global variables, motion parameters and solver were set in EDEM software. The motion characteristics and mixing uniformity of concrete materials were analyzed by discrete element simulation. The orthogonal experiment shows that the best combination of mixer mixing parameters was when the shovel plate installation angle is 45˚, the mixing speed is 35 rpm, and the filling ratio is 0.4, which provides a reference for the design and production of the vertical mixer.
