摘要

离散元法(DEM)是获得颗粒运动的定性和定量信息的有效工具,有助于农业装备结构的设计和优化。DEM模拟参数的准确性对模拟结果影响很大。本研究采用高速相机测量、DEM模拟和验证试验相结合的方法,确定了肥料颗粒的物质和相互作用特性参数。测定了3个肥料品种的基本参数(三轴尺寸、堆积密度、密度、静摩擦系数)和肥料与物料之间的恢复系数。不同料板与肥料颗粒之间的休止角有显著差异。采用Box-Behnken方法对恢复系数和颗粒间滚动摩擦系数的定标值进行了优化。肥料颗粒间的静摩擦系数和滚动摩擦系数对休止角有显著影响。肥料颗粒间恢复系数、静摩擦系数和滚动摩擦系数的测定值分别为0.323、0.381和0.173。在最优模拟参数下,休止试验角度误差小于3.0%,每行一致性变异系数小于1.68个百分点。利用实测参数进行休止角DEM模拟和各排一致性变异系数测试,可以较准确地预测实验结果。本文的研究结果为肥料颗粒的DEM研究提供了理论依据。

Determination of Material and Interaction Properties of Granular Fertilizer Particles Using DEM Simulation and Bench Testing
The discrete element method (DEM) is an effective tool for obtaining qualitative and quantitative information on particle motion, which aids in the design and optimization of agricultural equipment structures. The accuracy of the DEM simulation parameters significantly impacts the simulation results. This study employed a combination of high-speed camera measurement, DEM simulation, and validation tests to determine the material and interaction property parameters for fertilizer particles. The basic parameters (triaxial size, bulk density, density, and coefficient of static friction) and coefficients of restitution between fertilizer and material were measured for three fertilizer varieties. There was a significant difference in the angle of repose between various material plates and fertilizer particles. The calibration values of coefficients of restitution and coefficients of rolling friction between fertilizer particles were optimized using the Box–Behnken method. The angle of repose was significantly affected by the coefficient of static friction and the coefficient of rolling friction between the fertilizer particles. The determined values for the coefficient of restitution, coefficient of static friction, and coefficient of rolling friction between the fertilizer particles were 0.323, 0.381, and 0.173, respectively. The error in the angle of the repose test was less than 3.0%, and the variation coefficient for each row consistency was less than 1.68 percentage points under the optimal simulation parameters. DEM simulations of the angle of repose and each row consistency variation coefficient test using the measured parameters can accurately predict the experimental results. The findings of this paper provide a theoretical basis for the DEM study of fertilizer particles.

期刊介绍: Agriculture (ISSN 2077-0472) is an international and cross-disciplinary scholarly and scientific open access journal on the science of cultivating the soil, growing, harvesting crops, and raising livestock. We will aim to look at production, processing, marketing and use of foods, fibers, plants and animals. The journal Agriculturewill publish reviews, regular research papers, communications and short notes, and there is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental and/or methodical details must be provided for research articles.
