旋耕刀滑切角及滑切角方程的研究

Research on Grass-removing Angles and Equations of Rotary Blades

详细论述了旋耕刀滑切角及各种滑切角之间的关系,推导了正刃动态滑切角方程,变换该方程的参数,可以得到其它滑切角方程,从而把各种滑切角统一在同一个方程中。

In this paper, a detailed description on the grass-removing angles of rotary blades and the relationships between these angles are presented. The equation of the dynamic grass-removing angle for sidelong portion of the rotary blade is derived. This equation is a basic equation and it is universally applicable for rotary blades. It incorporates all the parameters of the grass-removing angles. By altering these parameters, other relevant equations can be obtained.
