Abstract

为了解决传统小区花生播种机断垄、塌垄的问题，本文设计了一台双镇压辊结构小区花生播种机，并采用基于DEM-MBD耦合的方法建立了机具作业过程的仿真动力学模型。通过参数化建模、选用合理的力学模型、获取仿真所需参数和设置仿真参数等一系列操作完成了耦合模型的建立。仿真结果表明，播种仿真实验得到速度越慢，起垄质量越高；进行播种均匀性分析得到各穴距基本保持一致；进行覆土和镇压分析得到播种单体工作速度增大，横向和纵向的位置变化呈现逐渐变大趋势。通过对比仿真结果与田间试验结果，验证了仿真试验的有效性。研究表明，基于DEM-MBD耦合的方法为小区花生播种机作业性能评价和机具设计提供了一种新研究方法。
