摘要
利用预测模型的计算机程序,计算了耕作阻力与耕作速度、耕深、耕宽、切削角的关系。结果表明,这些关系均与以往的试验结果近似。多种实际工况的计算值与室内土槽试验结果的对照表明,二者相符较好,从而定量地验证了预测模型的合理性。
The relations between cutting resistances of simple tillage cuts and cutting speed, depth,width and rake angle are calculated with the computer-programmed prediction model, which are similar to the results obtained by other researchers.The soil bin test in cases of a blade and a tine under several different soft and working conditions is carried out.The results are consistent to those calculated.
