Owing to high center of mass and heavy tractor body, the high-power wheeled tractor has a tendency to bump when it drives on the bumpy farmland during high-speed transportation. Especially the frequency of the excitation from ground is approximately the inherent frequency of the front axle suspension, which will result in handling stability and ride comfort or even endangering security of its driving. Based on it, through comprehensively considering the simulations control of body vibration acceleration and displacement of suspension and the nonlinear control of suspension system in the process of filling a discharging oil, a damping scheme for front axle suspension of high-power wheeled tractor was put forward. Firstly, the front axle suspension damping system was designed, and a 1/4 tractor vibration model with front axle suspension was established. Secondly, based on the control characteristics of the front axle suspension, a hierarchical control algorithm based on the reference sky-hook and ground-hook model for active suspension system was proposed. The simulation model was constructed by using Matlab/Simulink and compared with the conventional PID algorithm. The simulation results indicated that the hierarchical algorithm was better than the PID control. Finally, the HILS platform of the control system and the indoor test platform of the front axle suspension system were built, at the same time, the suspension vibration control strategy gest verification was carried out. The test results showed that the hierarchical control algorithm based on the reference sky-hook and ground-hook model can quickly adjust the control parameters, the root mean square of the body vibration acceleration of the designed suspension system was reduced to about 2.36m/s2, which was 55.8% lower than that of the passive suspension. At the same time, the root mean square of the suspension dynamic deflection was limited to a small range, which was obviously better than passive suspension system, and met the vibration reduction requirements of the front axle suspension of high-power wheeled tractor. The test results were well matched with the simulation results, which verified the effectiveness of the vibration reduction scheme. Thereby, the research result can provide reference for the design and development of the front axle active suspension system for high-power wheeled tractor.
