According to poor mechanical performance such as passing and leveling difficult in hilly areas, the terrain adaptive and dynamic leveling agricultural chassis for hilly area was designed. Four groups of leveling suspension’s cantilever angle can be precisely adjusted, so the chassis can not only have the capability to adjust its own configuration to accommodate to the terrain with which it interacted and contacted, but also can locomote continuously along the ground curve of terrain surface as far as possible, moreover, it also can realize the body leveling control through the suspension’s cantilever angle adjustment. The design scheme can resolve the two problems during the chassis locomotion on the uneven ground. During the terrain adaptive locomotion, the tilt sensor can measure the inclination angle of the chassis body in real time, so the instantaneous cantilever angle adjustment value of each suspension can be calculated. And the dynamic compensation leveling of the chassis can be realized by adjusting the cantilever angle of each suspension accurately. Three-dimensional model was established by using 3D modeling software referring to Dongfanghong 500 tractor, and the model was imported into dynamic analysis software ADAMS for simulation analysis. By analyzing the simulation process, the chassis can achieve dynamic leveling control so well that the accuracy of both roll angle and pitch angle just was within 0.5°. A small scale prototype was developed and tested in the soil bin, and the chassis can perform dynamic leveling control so well that the accuracy of both roll angle and pitch angle just was within 1° during terrain adaptive locomotion with multi DOF. The simulation, experiments in the soil bin or on the natural ground can verify the theoretical analysis and calculation results, and provide reference for the application of terrain adaptive and dynamic leveling agricultural chassis in the hilly area.
