摘要
为进一步提升我国联合播种机的综合播种效率,基于迭代计算模型理论针对其整机核心结构组件展开优化研究。通过搭建用于深度实现整机作业性能参数迭代优化的数学模型,考虑作业过程中部件振动与结构之间的关系,进行合理化的三维机构设计与振动仿真,并实施此迭代优化下的联合播种机实地作业试验。试验结果表明:经迭代优化后的联合播种机关键作业效能均得到明显改善,播种合格率和种子利用率分别相对提高了6.72%和8.79%,最佳作业频率阈值为14~16Hz,播种系统的作业稳定性与作业效率均提升至92%以上,可为种植装备的改进提供思路与方法。
In order to further improve the comprehensive sowing efficiency of China's combined planter,the optimization of the core structure components of the whole machine was carried out based on the iterative calculation model theory.By building a mathematical model for in-depth iterative optimization of the operating performance parameters of the whole machine,considering the relationship between component vibration and structure in the operation process,the rationalized three-dimensional mechanism design and vibration simulation were carried,field operation test of the combined planter under this iterative optimization was carried out,and the results showed that the key operation efficiency of the combined planter after iterative optimization had been significantly improved,in which the qualified rate of sowing and the utilization rate of seeding had been relatively increased by 6.72%and 8.79%respectively,and the optimal operation frequency threshold of the combined planter was 14-16Hz.The operation stability and efficiency of the whole sowing system also had been increased to more than 92%.The application test of iterative optimization had a good effect,which would be an important practical connotation for the application parameter setting and structure optimization of current sowing operation,and could provide ideas and directions for the improvement and innovation of the similar agricultural machinery planting equipment.
