摘要
在掘削土的过程中 ,当刀板运动方向与刀刃线垂直时为平面掘削状态 ,即二维掘削模式。当刀板运动方向与刀刃线不垂直时 ,土在刀板上的运动状态发生很大变化 ,并与刀板的几何参数密切相关 ,这时为空间掘削状态 ,即三维掘削模式。本文探讨了三维掘削模式下刀具几何参数的影响 ,并通过试验进行了分析。
In process of earth cutting when the motion direction of the cutter is perpendicular to its edge line,there is plane cutting condition,that is,two dimensional cutting mode.When the motion direction of the cutter is not perpendicular to its edge line there is three dimensional cutting mode.This paper inquires into the effect of cutter geometrical parameter under three dimensional cutting mode and analyses it through experiment.
