横向割断机构是草方格铺设机器人横向铺设系统中一个重要的组成部分,直接影响机器人的正常运行。针对草方格铺设机器人所要完成的任务,设计出一套既适合工作环境、又能完成割断任务的新型机构。应用计算机仿真技术,利用Pro/ENGINEER软件绘制出割断机构的三维模型,观察模型设计是否存在干涉等现象;利用ADAMS软件对割断机构进行动力学仿真,通过仿真观察机构的运行,绘制出关键部位的速度、位移等参数曲线,在理论上确保割断机构动作方面的可行性、合理性;最后通过实验验证横向割断机构能够按设计完成割断草帘绳的任务。
The transverse cutting mechanism is an important part of the horizontal laying system of the grass checkered laying robot and directly affects the normal operation of the robot. In view of the tasks to be completed by the grass checkered laying robot, a new type of mechanism is designed which is suitable for the working environment as well as for the task of cutting off. Using computer simulation technology, using Pro / ENGINEER software to draw a three-dimensional model of the cutting mechanism to observe the model design for the existence of interference and other phenomena; the use of ADAMS software to simulate the cutting mechanism, observation mechanism through the simulation operation, draw the key parts Speed, displacement and other parameter curves, in theory to ensure the action of the cutting mechanism is feasible and reasonable. Finally, the experiment verified that the transverse cutting mechanism can finish the task of cutting the grass rope according to the design.
