    摘要:

    針對(duì)輪邊電驅(qū)動(dòng)鉸接式礦用汽車的結(jié)構(gòu)及轉(zhuǎn)向特性,提出一種以滑移率一致為控制目標(biāo)的差速控制策略。建立輪邊電驅(qū)動(dòng)鉸接式地下礦用汽車運(yùn)動(dòng)學(xué)和動(dòng)力學(xué)模型,分析轉(zhuǎn)向時(shí)各輪運(yùn)動(dòng)關(guān)系及受力狀況;利用加速度傳感器在樣車上測(cè)試車體實(shí)際速度,并采用Kalman濾波方法估算出車體速度真實(shí)值,與所搭建的滑移率控制器聯(lián)合對(duì)轉(zhuǎn)向差速工況進(jìn)行仿真。結(jié)果表明:經(jīng)濾波后的信號(hào)延時(shí)小,響應(yīng)速度快,可直接估計(jì)車速。輪邊電驅(qū)動(dòng)鉸接式地下礦用汽車采用以滑移率一致為目標(biāo)的差速控制策略優(yōu)于等扭矩控制,在試驗(yàn)轉(zhuǎn)彎工況下內(nèi)外側(cè)輪滑移率皆可穩(wěn)定為-0.08,不存在拖滑情況,使地面附著系數(shù)得到充分利用,達(dá)到功率的合理分配。該控制策略對(duì)減小輪邊電驅(qū)動(dòng)鉸接式車輛輪胎磨損,提高驅(qū)動(dòng)功率利用率具有實(shí)際意義。

    Abstract:

    Aiming at the special structure and steering characteristic of wheeled electric-driven articulated underground mining truck, a differential control strategy which took the equal slip rate as control target was given. The kinematic and dynamic model of electric-driven mining ADT was established and the kinematic relationship and stress condition of the driving wheels were analyzed during steering. Acceleration sensors in the sample ADT were used to test the actual speed of the vehicle. Results showed that the filtered signal had small delay and fast response and could be directly used to estimate the speed. Equal slip rate control strategy was superior to equal torque control strategy because it could make full use of the ground adhesion coefficient and achieved the reasonable distribution of drive power. Two sides wheel slip ratio could be stable on -0.08 and the sliping phenomenon was avoided in experimental turning. This control strategy has practical effect for reducing tire wear and improving driving power utilization.
