摘　　要：为提高丘陵山地农业机械利用率,设计了一种挂载悬挂装置的电动履带底盘。在对履带底盘关键部件进行设计计算与选型的基础上,以通过复杂地形为目标,对履带底盘的通过性能进行了理论分析,并借助多体动力学软件RecurDyn对整机进行两种路面下的多体动力学仿真分析,获得了底盘在横向与纵向坡地及翻越垂直壁障与跨越壕沟的相关运动参数。仿真结果表明:在两种路况下履带底盘均能平稳通过25°的横向斜坡和跨越185 mm的垂直壁障。在干砂路况下履带底盘的最大纵向爬坡角为45°,最大跨越壕沟宽度为510 mm。在黏土路况下履带底盘最大纵向爬坡角为28°,最大跨越壕沟宽度为560 mm。设计的履带底盘满足在复杂地形下的行驶通过性要求。In order to improve the utilization rate of agricultural machinery in hilly and mountainous region,a electric crawler chassis with suspended hanging device was designed.Based on design calculation and selection of key components of the chassis,the theoretical analysis of passing ability of the chassis was carried out with the goal of passing through complex terrain.The chassis was simulated using the multi-body dynamics software RecurDyn under two road conditions,and the relevant motion parameters of the chassis in crossing a 25° lateral slope,climbing a vertical barrier of 185mm,and crossing a ditch were obtained.The simulation results showed that the chassis could smoothly pass through a 25° lateral slope and climb a vertical barrier of 185mm under both road conditions.In the sandy road condition,the maximum longitudinal climbing angle of the chassis was 45°,and the maximum crossing ditch width was 510mm.In the clay road condition,the maximum longitudinal climbing angle of the tracked chassis was 28°,and the maximum crossing ditch width was 560mm,which met the design requirements for the passing ability of the chassis in complex terrain.
