茎秆折断在玉米收获过程中已成为一个迫切需要解决的问题。为此，通过 ADAMS／VIEW 拉伸法建立玉米茎秆柔性体模型，利用Pro／E建立割台三维模型，导入 Adams 后添加相应约束和驱动进行仿真。仿真结果表明：分禾器外表面过渡处越平滑，植株越不易被推倒，减少了玉米茎秆的折断的几率。同时，通过虚拟正交试验，得到拉茎辊转速和机器行走速度的最优组合为n＝900r／min，v＝2．16km／h，可以降低对玉米茎秆的损伤程度，减少折断玉米茎秆的几率。

Maize culm snapped has become an urgent problem to be solved in the course of the corn harvest .The flexible body of maize culm was being created by ADAMS/VIEW Extrusion .The model of maize harvester header was established with Proe .And then , these models were imported into the ADAMS environment to create the virtual prototyping models including the appropriate constraints and motion , and drive simulation .Simulation results show that: the divider outside the smoother surface transitions ,the plant can not easily be torn down , reducing the chance of snapped the maize culm . Through virtual orthogonal experiment , snapping roller rotational speed and travel speed of the optimal combination for n=900r/min,v=2.16km/h, can reduce the extent of damage to the corn stalk , reducing the chance of snapped the maize culm .
