丘陵山地是我国果园的重要种植区,由于丘陵山地果园种植环境较为恶劣、空间郁闭,大中型履带式动力底盘的作业质量受到严重影响.针对大中型履带式动力底盘普遍存在转向不灵活、越障性能差等作业困难问题,为了增强丘陵山区果园履带式动力底盘的环境适应能力和通过能力,设计了一种适应丘陵山地果园复杂环境的小型履带式动力底盘.小型履带式动力底盘爬坡能力强、越障性能好、能够在行间1.2m的果园环境中灵活作业,在多体动力学软件RecurDyn中建立动力学模型,对小型履带式动力底盘在硬质和松软两种路面环境下的直线、爬坡和越障3种行驶过程进行仿真分析.结果表明,小型履带式动力底盘的通过性和适应性满足作业要求,该研究能够为丘陵山区小型履带式动力底盘的设计提供理论支持和参考依据.
Hilly and mountainous areas are critical regions for orchard cultivation in China.Due to harsh planting environment and dense foliage in these orchards,operational quality of large-and-middle-sized tracked power chassis systems is severely compromised.Addressing common issues such as poor maneuverability and inadequate obstacle clearance capabilities,a small-scale tracked power chassis was designed specifically adapted for complex environments of hillside orchards.This chassis boasted strong climbing abilities and excellent obstacle clearance,allowing for flexible operation in orchard rows with a spacing of 1.2 meters.Using multi-body dynamics software RecurDyn,a dynamic model of tracked chassis was developed.Simulations were performed to analyze its performance in straight-line motion,climbing,and obstacle clearance on both hard and soft terrains.Results indicated that chassis'passability and adaptability met operational requirements.This study could provide theoretical support and a reference for design of small-scale tracked power chassis in hilly orchard areas.
