基于谷物脱粒中自由籽粒的运动轨迹与速度的拟合分析

Based on grain threshing free grain trajectory and speed of fitting analysis

以螺旋叶片、刀齿组合式轴流脱粒与分离装置为研究对象,利用Matlab画图分析了稻谷脱粒后籽粒的运动轨迹与速度,通过使用Matlab画出的轨迹与速度图与以往的使用Excel画法画出的图进行了对比分析,结果显示Matlab画出来的图在精确度、清晰度等方面要好于Excel画法。

with spiral leaf,cutter tooth combined-type axial flow threshing and separating installation as the research object,using Matlab drawing analyzed after threshing rice grain trajectory and speed,through the use of Matlab draw the trajectories and velocity diagram with before the use of Excel brushwork draw the graph compares the,draw the conclusion,this paper has drawing method painted chart in precision,legibility aspects better than the old Excel representations.
