摘要
为提升小型农用履带车辆在南方丘陵山区复杂环境下作业的适应能力,对某型小型农用履带车辆在定型农业路况下的通过性进行仿真与分析。利用Creo三维软件建立小型农用履带车辆的三维模型并导入多体动力学分析软件RecurDyn,对农用履带车辆在两种路面(硬质、软质)的平地直线行驶、3种沟宽(400mm、700mm、900mm)的越沟通过性、3种障碍物高(150mm、260mm、380mm)的越障通过性、3种斜坡(10°、20°、30°)的爬坡通过性进行仿真,分别得到农用履带车辆运动学规律,为进一步优化农用履带车辆结构提供参考依据。
In order to improve the adaptability of small agricultural tracked vehicles in the complex environment of southern hilly and mountainous areas,the mobility in typical agricultural terrains of the small agricultural tracked vehicle was simulated and analyzed.The kinematics laws of agricultural tracked vehicles were obtained through the 3D software Creo and multi-body dynamics software Recurdyn.The simulation was carried out for the agricultural tracked vehicle running straight on flat ground with two kinds of road surfaces(hard and soft),and ditch crossing performance of three trench widths(400mm,700mm,900mm),and obstacle crossing performance of three obstacle heights(150mm,260mm,380mm),and climbing performance of three slopes(10°,20°,30°).The kinematic laws of agricultural tracked vehicles are obtained,which provides a reference for further optimizing the structure of agricultural tracked vehicles.
