指出《规范》公式中的主要参数均基于线性(弹性工作阶段)分析，对结构实际工作阶段(包括弹塑性、塑性工作阶段)由于损伤累积而引起结构性能的变化涉及较少，对常见的偏压构件的刚度计算也未作专门规定，这使得以往内力计算较为粗糙。 |
| 10. | Aiming at the defects of the imc - 70 model stubble - plastic film residue collector that the draft is rather great and the plastic residue or stubble are sometimes left out in the operation process , formulas for the principal parameters of the knives have been driven out based on the analysis of the distribution manner in the field of the stubble and plastic film residue , the variation range and the variation tendency of the principal parameters for the reduction of the draft have been found on a trial basis in the corn field through theoretical analysis and experimental study and a mathematical model for the draft applied on the knives has been established in accordance with the movement and distortion of the soil under the action of the knives
本文针对1mc ? 70型地膜回收起茬机起膜、起茬铲刀在作业中阻力大，残膜、根茬有漏起的现象，通过对作物收获后残膜、根茬在田间分布情况的分析，推导出铲刀满足生产要求主要参数的求取方法和公式，并经理论分析和试验研究，确定了铲刀对玉米茬地进行起膜、起茬时主要参数的取值范围和减小牵引阻力各参数的取值规律。以铲刀作用下土壤的运动变形为基础，建立了铲刀牵引阻力模型。 |
