本文主要研究内容
作者郝建军,于海杰,赵建国,李建昌,马志凯,蔡金金（2019）在《楔形减阻旋耕刀设计与试验》一文中研究指出：为解决旋耕整地作业阻力大、能耗高等问题,该文基于旋耕刀理论受力模型设计了一种楔形减阻旋耕刀。采用Inventor和HyperMesh软件分别创建国标旋耕刀及楔形减阻旋耕刀的三维模型和切削土壤模型,分析了楔形减阻旋耕刀的应力强度,对比了国标旋耕刀与楔形减阻旋耕刀的切削阻力。通过田间试验对比了国标旋耕刀与楔形减阻旋耕刀的扭矩、功耗与碎土率。结果表明:楔形减阻旋耕刀所受最大应力为29.49 MPa,远小于材料的屈服强度430 MPa,在保证刀身强度的前提下,与国标旋耕刀相比,楔形减阻旋耕刀质量减轻8.3%;平均切削阻力较国标旋耕刀下降10.65%。在相同工况条件下,楔形减阻旋耕刀的平均扭矩为648.916 N·m,较国标旋耕刀下降11.35%;楔形减阻旋耕刀的平均功耗为67.3kW,较国标旋耕刀下降9.29%,碎土率提高4%,耐磨性能与国标旋耕刀持平,能够达到在降低作业功耗的同时,提高耕作质量并保证刀具使用寿命。
