    摘要:

    設(shè)計(jì)了裝載機(jī)線控轉(zhuǎn)向技術(shù)硬件在線回路仿真系統(tǒng)并介紹了其組成工作原理，采用比例溢流閥加載的方式對(duì)系統(tǒng)進(jìn)行模擬加載。利用傳遞函數(shù)法建立了仿真系統(tǒng)的數(shù)學(xué)模型，并在Matlab中對(duì)其進(jìn)行了仿真與PID參數(shù)的調(diào)整。利用該硬件在線回路仿真系統(tǒng)分別對(duì)不同的輸入信號(hào)及不同負(fù)載條件下的響應(yīng)進(jìn)行了實(shí)驗(yàn)，實(shí)驗(yàn)結(jié)果表明，采用比例溢流閥加載的方式可以較好地對(duì)系統(tǒng)進(jìn)行模擬加載，線控轉(zhuǎn)向技術(shù)在裝載機(jī)上應(yīng)用是可行的。

    Abstract:

    The composing and the function of every part of hardware-in-the-loop simulation system of steer-by-wire technologies on wheel loader were presented. The proportional relief valve to simulate the load of the system was introduced. Making use of the means of transfer function, the mathematics model of the system was built, and with the model, the system has been simulated, then the PID parameters in Matlab were regulated. An experiment was carried out on the hardware-in-the-loop simulation system to test the response with different input signals and loads. The result showed that it is well simulated the load by means of proportional relief valve, validated the feasibility of the use of steer-by-wire technologies on wheel loader.
