中文摘要：

传统式芯铧式开沟器被广泛地应用于东北垄作地区,但其开沟宽度大、与土壤产生的阻力大限制其使用。为此,对芯铧式开沟器的结构特点进行研究,确定了开沟器宽度d、入土角α、斜面角β、作业速度v、含水率p为其性能的影响因素,用Solid Works软件建立了一系列不同参数的芯铧式开沟器模型。通过对耕层土壤的物理性质与力学性质的研究,运用EDEM对所设计的一系列芯铧式开沟器进行仿真分析,得到开沟阻力较小的开沟器,其参数为:入土角为50°、斜面角为55°、宽度为50mm。在室内土槽中,进行芯铧式开沟器的性能测试。结果表明:仿真与试验数据具有一定的相关性,且规律基本一致,验证了仿真模型参数选取的正确性。

英文摘要：

Traditional type furrow opener is widely used in the Northeast ridge area, but the width of the ditch, and soil resistance restrict the use it.In this paper, the structural characteristics of core ploughshare type furrow openers, deter-mine the width of opener D, penetrating angle alpha, bevel angle beta, operating speed V, water rate P for the factors affecting the performance of, with the SolidWorks software established a series of different parameters of core ploughshare type furrow opener model.Through the study on soil physical properties and mechanical properties, using edem to simu-lation and analysis of the designed a series of core ploughshare type furrow opener and opener ditching resistance is rela-tively small, its argument is:penetrating angle of 50 degrees, slope angle of 55 degrees, width is 50mm.In the indoor soil tank, testing the performance of furrow opener.The results show that the simulation and test data have a certain cor-relation, and the law is basically consistent, and verify the correctness of the simulation model parameters.
