山地电动履带底盘设计与仿真分析

Design and Simulation Analysis of Mountain Electric Track Chassis

针对丘陵山区地形起伏大、地块碎小、土壤粘重等复杂的农机作业背景,以及现有农机作业对高效、安全、环保的履带底盘需求日益增长的现状,设计制造了一种山地电动履带底盘。通过Solidworks软件建立履带底盘模型,并借助Adams多体动力学仿真软件对底盘的爬坡、过沟和越障性能进行了动力学仿真。仿真结果表明,最大爬坡角度为25°,最大过沟宽度为400 mm,最大跨越垂直障碍物高度为200 mm,仿真试验验证了底盘在行驶过程中的可行性,为进一步优化丘陵山区农业机械底盘结构提供了参考。

Aiming at the complex agricultural machinery operation background of hilly and mountainous areas with large terrain,small plots and heavy soil,and the increasing demand for efficient,safe and environmentally friendly caterpillar chassis in existing agricultural machinery operations,a mountain electric caterpillar chassis was designed and manufactured.Solidworks software was used to establish the track chassis model and Adams multi-body dynamics simulation software was used to conduct dynamic simulation on the slope climbing,ditch crossing and obstacle crossing performance of the chassis.The simulation results showed that the maximum slope climbing Angle was 25°,the maximum ditch width was 400 mm and the maximum vertical obstacle crossing height was 200 mm.The simulation test verifies the feasibility of the chassis in the driving process,and provides a reference for further optimizing the chassis structure of agricultural machinery in hilly and mountainous areas.
