Research on Vibration Reduction System of Agricultural Tractor Based on Hierarchical Control System
In order to solve the tractor in high-speed transport operations by the unevenness of the road,prone to violent bumps and vibrations and other problems,improve the tractor handling stability and smoothness of driving,this paper is the front axle active suspension damping as the research goal,proposed a layered control system based on agricultural trac-tor damping system research,the system uses a multi-stage damping structure,the whole damping control process is di-vided into three levels.The system adopts a multi-stage damping structure and divides the whole damping control process into three layers:sensor layer,control layer and execution layer,which realize the functions of data acquisition,signal processing,control command generation and execution.Finally,through simulation and experimental verification,the re-sults show that the system can significantly reduce the vibration of agricultural tractors,and the control performance of the layered algorithm is better than conventional PID control.The research results provide technical reference and theoretical reference for improving the stability and comfort of driving,and have good application prospects.
