    摘要:

    本文针对适用于丘陵山地地区拖拉机自走底盘车身调平过程自动化程度低的问题,对拖拉机底盘结构、控制系统原理、双轴倾角传感器和系统压力传感器的配置及排布等方面进行了研究,对拖拉机底盘调平过程中液压油输出不稳定现象及控制策略进行了归纳,提出了一种基于HMI(HC-SUK8070)、C470控制器及Codesys软件编制控制程序等车载自动控制技术的调平系统,利用履带式丘陵山地拖拉机车身调平过程中对液压系统、传感器、电磁比例阀响应时间进行了测试。研究结果表明,该自动调平系统能实时监测车身调平过程中的各项参数,能够实现操作互锁、过载响应、自走底盘车身自动调平,提高了丘陵山区拖拉机自走底盘车身调平的自动化程度。

    Abstract:

    Aiming at the problem of low automation degree in the auto-leveling process of self-moving tractor chassis and body in hilly and mountainous areas, the structure of tractor chassis, the principle of control system, the configuration and arrangement of double-shaft inclination sensor and system pressure sensor were studied and the control strategy for the instability of hydraulic oil output in the leveling process of tractor chassis was summarized. The self-adjusting control system was designed and developed which included HMI(HC-SUK8070), C470 controller,Codesys software control program, etc. In the process of auto leveling test, the response time of hydraulic system,sensor and electromagnetic proportional valve were tested. The test results indicated that the established automatic leveling system could monitor the parameters in the process of body leveling in real time and realize the operation of interlock, overload response, auto leveling of body and chassis, better improving the automation degree of the chassis-body leveling.
