Dynamic simulation and analysis of smallelectric crawler vehicle
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.
