摘  要:
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。

摘  要:
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= 900 r / min,v = 2. 16 km / h,can reduce the extent of damage to the corn stalk,reducing the chance of snapped the maize culm.
