摘要
针对丘陵山地中幼林抚育作业需求,设计一种履带式割草机行走装置并确定其关键参数。利用三维机械设计软件(solidworks,SOLIDWORKS)和机械系统动力学自动分析(automatic dynamic analysis of mechanical systems,ADAMS)软件,建立行走装置三维模型及动力学模型,通过仿真分析验证其在丘陵山地地形中的通过性,并针对仿真结果进行优化。结果表明,行走装置在35°斜坡上能保持稳定牵引性能;翻越150 mm垂直障碍时可平稳通过且不倾覆;通过500 mm宽沟壑时能维持良好稳定性;优化后的行走装置质心位移和速度波动幅度减小,稳定性提升。该履带行走装置在复杂地形中展现出优良的通过性和稳定性,有效解决丘陵山地割草机通过性差和稳定性不足的问题,对提升丘陵山地地区林业机械化水平具有重要意义。
Abstract
In response to the needs of young and middle-aged forest tending operations in hilly and mountainous areas, a crawler traveling device for a mower was designed, and its key parameters were determined. Using 3D mechanical design software (solidworks, SOLIDWORKS) and automatic dynamic analysis of mechanical systems (ADAMS) software, a three-dimensional model and a dynamic model of the crawler traveling device were established. The passability of the crawler traveling device in hilly terrain was verified by simulation analysis, and the simulation results were optimized. The results showed that the crawler traveling device can maintain stable traction on a slope with a gradient of 35°; it can smoothly cross a 150 mm vertical obstacle without tipping over; and it can maintain good stability when crossing a gully 500 mm wide; the centroid displacement and velocity fluctuation amplitude of the optimized traveling device were reduced, and the stability was improved. The crawler traveling device demonstrates excellent passability and stability in complex terrain, effectively solving the problems of poor passability and insufficient stability of mowers in hilly and mountainous areas. It is of great significance for improving the level of forestry mechanization in these regions.
