摘要
设计一款小型履带式底盘,可搭载多种设备,完成运输、喷雾等果园作业需求,利用多体动力学软件进行仿真分析验证其在山地果园中的通过性能。根据山地果园种植规律,搭建履带式底盘模型结构,基于Bekker理论分析履带式底盘在行驶时的受力情况;构建多体动力学模型,创建水平地面和连续斜坡(10°、15°、20°)在黏土地面进行运动仿真,设置三种宽度(150 mm、250 mm、350 mm)的沟壕,开展不同速度下的履带爬坡和越沟仿真试验。最后提取履带底盘在水平地面、斜坡和沟壕运动仿真后的数据曲线,拟合后对比分析履带底盘在复杂环境下的通过性能,并得出结论:通过多体动力学仿真验证所设计的小型履带式底盘在果园崎岖地形的行驶性能,为小型农用履带式底盘研究提供参考。
A small crawler chassis is designed,which can carry a variety of equipment to complete the orchard operation requirements such as transportation and spraying.The multi-body dynamics software is used for simulation analysis to verify its passing performance in mountainous orchards.According to the planting law of mountain orchard,the model structure of tracked chassis is built,and the force of tracked chassis is analyzed based on Bekker theory.A multi-body dynamics model is constructed to create a horizontal ground and a continuous slope(10°,15°,20°)for motion simulation on the clay ground.Three widths(150 mm,250 mm,350 mm)of the trench are set up to carry out crawler climbing and ditching simulation tests at different speeds.The data curves of the tracked chassis after the simulation of horizontal ground,slope and trench motion are extracted,and the passing performance of the tracked chassis in complex environment was compared and analyzed after fitting.The driving performance of the designed small crawler chassis in the rugged terrain of the orchard is verified by multi-body dynamics simulation,which provides a reference for the research of small agricultural crawler chassis.
