摘　　要：通过对圆柱型犁体曲面的犁耕阻力分析 ,找出了犁耕阻力与犁体曲率半径、水平元线角及土垡飞离犁体时与水平线夹角在铅垂面内的投影等参数之间的关系 ;推导出圆柱型犁体曲面犁耕阻力的修正公式。Through analysing plowing resistance of columniform plow surface was found the relationship among resistance and radium of plow surface and angle of plane line and projection angle between cold track and level line on plumb face when clod left plow;was educed the modifying formula of columniform plow surface plowing resistance.

关 键 词：圆柱形犁体曲面 犁耕阻力 修正公式
