摘要：

为获取浙江丘陵山区茶园土壤离散元仿真模型的精准接触参数,构建土壤离散元仿真模型,基于土壤堆积试验,结合试验测定和EDEM仿真构建土壤模型,以土壤堆积角为响应值,依次通过Plackett-Burman试验、最陡爬坡试验和Box-Behnken试验,逐级标定优化,得到如下最优参数组合:土壤-土壤的恢复系数0.49,土壤-土壤的静摩擦系数0.58,土壤JKR表面能13.06 J·m^-2。然后,通过线锤成孔仿真试验与现场试验对比分析,验证土壤仿真模型的准确性。结果显示,线锤在仿真土壤中的运动规律与实际试验基本一致,物理特性吻合,成型孔深误差为4.84%,表明土壤参数的标定和优化方法准确可行,构建的土壤模型可为后续开展茶园相关研究提供技术支撑。

Abstract:

In order to obtain the precise contact parameters of the discrete element simulation model for tea garden soil in Zhejiang, China, soil accumulation experiment was conducted, combined with experimental measurements and EDEM simulation. The soil accumulation angle was selected as the target value, step-by-step calibration optimization was carried out by Plackett-Burman test, the steepest ascent test and the Box-Behnken test to obtain the following optimal combination of soil simulation parameters: the soil-soil restitution coefficient of 0.49, the soil-soil static friction coefficient of 0.58, and the soil JKR surface energy of 13.06 J·m^-2. Further, the accuracy of the soil simulation model was compared and analyzed through the simulation test of wire hammer drilling and on-site testing. The simulation and on-site test results of the wire hammer drilling showed that, the characteristics and the movement law of the wire hammer in simulated soil was basically the same as the actual soil, and the relative error between the simulated result and the measured result of hole depth was 4.84%, which indicated that the discrete component simulation parameter calibration method of soil was accurate and feasible. The constructed soil model could provide technical support for subsequent research on tea gardens in Zhejiang.

Key words: discrete element method, parameter calibration, accumulation angle, simulation, soil
