基于离散元的颗粒肥料与PVC板之间的仿真参数的标定
Calibration of Simulation Parameters between Granular Fertilizer and PVC Plate Based on Discrete Elements
摘要
Abstract
Aiming at the problem that the discrete element simulation of the movement of granular fertilizer in the drain-age pipeline lacks accurate simulation parameters,a calibration method based on the simulation parameters between the granular material and the contact plate is proposed.Combining the real test results with the EDEM simulation experimental results,the collision recovery coefficient between the urea particles and the soft PVC plate was 0.302,the static friction factor was 0.525,and the rolling friction factor was 0.158,taking the urea particles and the soft PVC plate as the re-search object.After the accumulation angle test,the relative error between the real test and the simulation test is 4.3%,which proves the validity of the calibration parameters.关键词
