联合收割机速度对切割图中区域面积的影响

The Influence from the Speed of Harvester to Triangle Area on Incise Diagram

联合收割机是现代农业生产中实现收获机械化的最重要机具。在实际的收获作业中,由于田间作物及土壤状况的不同,联合收割机的工作速度不同,切割图中重割区、漏割区及1次切割区的面积也不同。现有资料只是定性地描述了机器工作速度对切割图中3个区域面积变化的趋势。为此,利用MATLAB软件对不同机器工作速度下切割图中3个区域的面积进行了计算,定量地描述了其变化规律。

Harvester is the most important implant to reach mechanization harvesting in modern agricultural production. In practical harvesting working, the working speed of harvester is different, so repeated cutting area, fail to cut area and one time cutting area are different because of different field and working condition. Some present materials describe the tendency of area influenced by the speed of machine qualitatively. So calculated 3 area on the cutting drawings by applying software MATLAB at different working speed of machine, described its variety regulation quantificationally.
