摘要
履带底盘具有接地比压小、转向灵活、机动性好等优异性能,不失为小型山地农业机械动力底盘的一种优选方案。文中以跨越壕沟宽度、攀越垂直障碍物高度为指标,对履带底盘常见行走装置的地形通过能力进行了评价,在此基础上提出了一种适用于丘陵山区农用机械的履带底盘设计方案,并借助多体动力学软件RecurDyn,对履带底盘在硬质、松软2种路面下直线、爬坡和越障行驶过程进行了仿真分析,验证了方案的可行性。研究成果为山地履带底盘的设计提供参考。
Crawler chassis has excellent performance such as low ground pressure,flexible steering and good maneuverability,which is regarded as an optimal scheme for small mountain-based agricultural machinery-driven chassis.In this article,the terrain-passing ability of the common walking device of the crawler chassis is evaluated,with the width of the ditch and the height of the vertical obstacle as the index.Thus,a crawler-chassis design scheme suitable for agricultural machinery in mountain areas is proposed.With the multi-body dynamic software RecurDyn,the simulation of the straight,climbing and obstacletraveling process of the crawler chassis under the hard and soft road conditions is carried out,and as a result,the scheme is feasible.The research will provide reference for the design of crawler chassis.
