走式不分行青饲机切割器滑切角分析与计算

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。

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

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.
