摘要
在联合收割机收获作业中,由于往复式切割器不同程度的磨损,使切割图中重割区、漏割区及一次切割区的面积也在不断地发生变化。为此,利用MATLAB软件,对标准往复式切割器在一定工作条件、割刀未磨损及磨损量分别为5%、10%、15%和20%时,切割图中3个区域的面积进行了计算,并定量地描述了割刀磨损量与切割图中3区域面积的变化规律。
In practical harvesting working, repeated cutting area, fail to cut area and one time cutting area are different because of abrasion of the cuter. So calculated 3 area on the cutting drawings by applying MATLAB at speed of machine at 4km/h, crank rotating speed at 449r/min and abrasion of cuter at 5%,10%, 15%, 20%, described its variety regulation quantificational.
