Discrete Element Simulation Study of Seed Metering Process of Inside-Filling Meter Based on EDEM
摘要
Abstract
Objective] To find the optimal meter rotational speed of seed metering. [Method] Discrete element simulation model was established for the Inside-Filling Meter. EDEM software was used for simulation study on seed metering property of inside-filling meter. Change trends of seed metering amount,seed-clearing starting angle,and seed-clearing ending angle of three varieties of peanut seeds were detected in different rotate speeds. [Result] When the rotate speed was 15. 7-45. 5 r/min,seed metering amount enhanced as the rotate speed increased,but had no corre-lation with peanut varieties. Seed starting angle and ending angle enhanced as the rotate speed increased,but the increase amplitude of starting an-gle was greater than that of ending angle,which led to the decrease of cleaning area with the increase of rotate speed. When the rotate speed was 38. 0 r/min,double grain rate reached the maximum value,and the uniformity of seed metering was the optimal. Change trend of simulation result was consistent with that of experimental results. [ Conclusion] It is feasible to analyze the inside-filling meter by discrete element simulation based on EDEM.关键词
