自走式不分行青饲机切割器滑切角分析与计算

Analysis and Calculation of Self-propelled Row no-Independent Forage Harvester Cutter's Sliding Cutting Angle

在对切割器进行动力学分析的基础上,给出了青饲机切割器动态切割角的定义和计算公式;详细分析了机器以不同作业速度行走时,切割器旋转1周过程中动态滑切角的变化规律,可按照统一方法描述滑切角的特性。同时,做出了动态滑切角增减量的函数曲线,该函数曲线对青饲机切割器的研究设计有重要意义,可直观看出滑切角的变化趋势,即青饲机作业速度越大,动态滑切角的变化幅度也越大。

In this paper, based on the mechanical analysis of the harvester＇ s cutter, the definition of the forage harvester＇ s cutter＇s dynamic sliding cutting angle and a calculating formula are rendered. When the forage harvester goes at different speed, the cutter＇s dynamic sliding cutting angle change is analyzed during whirling; the angle＇s equation is described by the same ways. At the same time, the curve of the sliding cutting angle is made, and the curve is important for the cutter＇ s design and study. The tendency of the angle is founded out directly through the curve, faster the harvester walks, more the dynamic sliding cutting angle changes.
