摘要
采用CAD软件虚拟设计了不分行玉米收获机分禾部件,阐述了实体模型的建立方法及过程,并应用机械系统动力学仿真软件MSC.ADAMS构建了三维运动仿真模型,实现了在ADAMS/View环境下分禾过程中拢入玉米茎秆的运动仿真。仿真表明,拨禾轮转速和作业速度对拢禾效果影响显著,指形拨禾杆末端形态对拢入玉米茎秆运动的影响值得注意。根据仿真结果对物理样机的设计提出了改进建议。
The feed-in mechanism model of a harvester has been researched based on the CAD software. The mechanical dynamics software MSC. ADMAS was used to establish the 3-D kinematic simulation model of corn stalks feed-in mechanism for no-row corn harvesting. The process of making kinematics model and its simulating were to set forth at length. The simulation based on software MSC. ADAMS was successfully got along. The results demonstrated that the harvesting speed and the rotating speed of finger rotor were main influencing parameters on the performance of the feed-in mechanism. The shape of finger rotator, especially the shape of the fingers＇ end, had a notable influence on the motion of corn stalks. Some ameliorative suggestions were provided to the corresponding physical mechanism.
