智能控制技术在履带式拖拉机上的应用研究

Study of Intelligent Control Technology on the Application of Tracklayer

为解决履带式拖拉机控制系统智能化程度不高、动力不足、环境适应能力不强的问题,针对其智能化控制系统进行了设计和改进。拖拉机采用分布控制管理系统进行控制,采用CAN总线实现通信,主要组成为总控制器、变速器控制、换挡/离合、油门控制器、转向控制器和悬挂控制器。通过对其履带式驱动桥进行改进,包括采用行星式转向机构和液压系统进行控制,提高了履带式拖拉机的动力和性能。实验室和田间试验结果表明:履带式拖拉机的控制系统可完成对拖拉机的智能控制,保证了其稳定行驶,能够满足拖拉机的设计和性能要求。

Aiming at the problem of unintelligence,insufficient motivation,and weakly adaptability to the environment of the tracklayer control system,the intelligent control system of tracklayer was designed and improved.The tracklayer was controlled of distributed control management system,and CAN bus to realize communication.It was constituted of total controller,transmission controller,shifting clutch,throttle controller,steering controller and suspension controller.The crawler drive axle was improved by using planetary steering mechanism and hydraulic system to improve the power and performance of the tracklayer.The test results show that the tracklayer control system could achieve intelligent control of the tracklayer,ensure stable driving.It could meet the design and performance of the tracklayer.
