基于2BYF-6型油菜免耕直播联合播种机旋耕开沟刀盘工作中所存在的强度不足问题,在强度许可的前提条件下,以开沟刀盘质量最小为目标建立优化模型,借助Matlab软件进行优化求解.结果表明,优化后开沟刀盘内孔直径50mm,安装6片刀片,刀盘厚度6mm,刀片安装螺栓孔位置尺寸360mm,结构优化后开沟刀盘质量较原产品降低10%.田间试验结果表明,优化后的产品单位时间无故障平均次数比优化前提高了200%.

Due to its insufficient intensity, with the target of minimizing its mass, an optimal model for disk of ditching knives of type 2BYF-6 rape combine seeder was established on permissible condition of intensity. By use of the matlab software, parameter after optimization is as follows： the inner hole＇s diameter of ditching knives disk is 50mm, the number of knives is 6, the thickness of knives disk is 6mm, the location dimension of the bolt on knife was 360mm, the mass of the knives disk after optimization reduced by 10%. Field test indicated, after being opt...
