    摘要:

    建立了拖拉機(jī)空間多體動(dòng)力學(xué)機(jī)械系統(tǒng)與線(xiàn)控轉(zhuǎn)向液壓系統(tǒng)聯(lián)合仿真模型，用Matlab編寫(xiě)了相應(yīng)的模糊PID控制仿真程序,，進(jìn)行了拖拉機(jī)線(xiàn)控轉(zhuǎn)向系統(tǒng)原地轉(zhuǎn)向仿真,。在平直水泥路面上進(jìn)行了鉸接擺桿式重型拖拉機(jī)線(xiàn)控原地轉(zhuǎn)向試驗(yàn)與行駛試驗(yàn),。試驗(yàn)研究表明,，所開(kāi)發(fā)的線(xiàn)控轉(zhuǎn)向系統(tǒng)能用于行駛速度小于13 km/h的作業(yè)工況,。

    Abstract:

    According to the structural characteristics of heavy articulated wheel tractor,a steer-by-wire system of the tractor was set up, consisted of electrical control system, angular displacement sensors, mechanical system and hydraulic steering system. The equivalent mathematical model of hydraulic steering system of the tractor was set up with nonlinear state space method by 12 parameters. Controlled by fuzzy self-tuning PID system, the articulated tractor simulation programs consisted of multi-body dynamics system and hydraulic system were developed, with help of Matlab software. The in-situ steering simulations of the tractor with the steering by wire system were carried out. Experiments on rigid road were carried out, and the results showed that the steering by wire system was suitable to the tractor operation condition when the speed was less than 13 km/h.
