    基于工作小臂的履带式林木采育机越障能力分析与研究

    Obstacle-surmounting ability of harvester based on working boom.

    • 摘要: 为了提高履带式林木采育机的林地越障能力,在履带式林木采育机的基础上加装越障工作小臂。基于D-H法建立采育机杆系的运动学模型,通过计算获得加装工作小臂条件下林木采育机的理论越障高度。在ADAMS环境下进行动态仿真,对各仿真相关的运动学参数进行分析,并将理论、仿真数据与实测采育机越障高度数据进行比较,验证林木采育机杆系运动学模型的正确性及其越障能力的提升程度。结果表明:在斗杆全收回状态,采育机整机抬升角度为13°,越障高度为693 mm;在斗杆全伸开状态,采育机整机提升角度为6.3°,越障高度为330 mm。加装越障工作小臂的履带式林木采育机能够满足林区越障要求,为实现和满足其上山入林作业,更有效地翻越障碍物提供了理论依据。

       

      Abstract: In order to improve the obstacle-surmounting ability of the harvester,we propose to install a barrier boom on the harvester, and create a virtual prototype in solidworks. Kinematic model of the boom is established based on D-H method, and the theoretical obstacle-surmounting height of the harvesters is calculated. Dynamic simulation is carried out in the ADAMS environment, the kinematic parameters of the simulation are analyzed, and the theoretical result and simulation data are compared with the experimental data of the obstacle-surmounting test of harvester. The results show that lifting angle of the harvester is 13 degrees and obstacle-surmounting height is 693 mm when the bucket rod takes back. In another test, the lifting angle is 6.3 degrees and obstacle-surmounting height is 330 mm in the process of extending the bucket rod. The harvester of equipping working forearm can meet the requirements of the obstacle surmounting and our study provides a theoretical basis for the forest tracked harvesters working in the forest and crossing obstacles more effectively.
