摘要
丘陵山区地貌复杂多变,阻碍了中大型农用机械进场作业.为此,设计一款适用于山区的小型电动遥控式履带运输车,并以该运输车为研究对象,利用RecurDyn仿真运输车在山地纵横坡行驶等过程中的动力学性能.结果表明,运输车载重200 kg在黏土路面上行驶时,纵向上坡最大坡度角为40°,纵向下坡最大坡度角为37°,横坡行驶最大坡度角为27°.试验结果表明,运输车纵坡上坡的极限值与仿真结果的相对误差为 7.5%,吻合度较高.试验验证了在不同路面行驶时该运输车运行稳定,可满足目前山地运输车的使用要求.
Abstract
The complex and variable landscape of mountainous areas hinders the use of medium and large-sized agricultural machinery.Therefore,a small electric remote-controlled crawler vehicle suitable for mountainous areas is designed,and its dynamic performance on slopes is simulated and analyzed by using RecurDyn.The results show that when the vehicle is load-ed with 200kg and traveling on clay road surface,the maximum slope angle of longitudinal uphill is 40°,the maximum slope angle of longitudinal downhill is 37°,and the maximum slope angle of cross-slope driving is 27°.The test results show that the relative error between the limit value of longitudinal uphill and the simulation result is 7.5%.The vehicle operates stab-ly when traveling on different road surfaces,and can meet the current requirements for the use in mountainous areas.
