【摘要】：本論文基于與公司的實際項目,燕山大學(xué)趙靜一教授科研團(tuán)隊與北京百善重工有限公司針對成都地鐵二號線東延線的施工要求,合作開發(fā)的重型載重運輸車項目。本文主要是對載重運輸車的驅(qū)動系統(tǒng)控制算法優(yōu)化以及整車的設(shè)計可靠性方面進(jìn)行了研究。以期望為后續(xù)的改進(jìn)車型作參考設(shè)計。首先,在運梁車的開發(fā)設(shè)計過程中考慮的因素很多,我們重點對運梁車的主要執(zhí)行機構(gòu),懸掛升降機構(gòu)和轉(zhuǎn)向執(zhí)行機構(gòu)進(jìn)行了設(shè)計研究。另一方面在液壓系統(tǒng)的設(shè)計研究中,主要對電液驅(qū)動系統(tǒng)的方案選定,驅(qū)動系統(tǒng)液壓元件的選型設(shè)計,以及所選液壓元件的控制方式進(jìn)行了研究。其次,基于運梁車驅(qū)動系統(tǒng)的研究,通過建立載重運輸車驅(qū)動系統(tǒng)的數(shù)學(xué)模型,一方面是從驅(qū)動系統(tǒng)的功率匹配策略研究了運梁車驅(qū)動系統(tǒng)的節(jié)能控制;另一方面從泵控馬達(dá)驅(qū)動系統(tǒng)的控制策略入手,提出了新的自適應(yīng)控制算法的優(yōu)越性,為今后載重運輸車的驅(qū)動控制優(yōu)化提供了研究思路。從而進(jìn)一步提高了運梁車的可靠性。最后,對運梁車的整車進(jìn)行了可靠性研究。主要對運梁車的驅(qū)動系統(tǒng),轉(zhuǎn)向系統(tǒng),懸掛系統(tǒng),建立了可靠性框圖,同時也通過各個部分的可靠性數(shù)學(xué)模型,對液壓系統(tǒng)的各個部分進(jìn)行了可靠度預(yù)測仿真。并結(jié)合現(xiàn)場的調(diào)試試驗,重點對轉(zhuǎn)向系統(tǒng)和驅(qū)動系統(tǒng)的測試進(jìn)行了驗證說明。最后結(jié)合調(diào)試試驗時遇到的轉(zhuǎn)向系統(tǒng)問題,通過建立了運梁車整車的故障樹模型,創(chuàng)新性的運用灰關(guān)聯(lián)理論,快速定位載重運輸車的故障,減少了尋找故障所浪費的時間。
[Abstract]:Based on the actual project of the company, the research team of Professor Zhao Jingyi of Yanshan University and Beijing Beshan heavy Industry Co., Ltd. have developed the heavy-duty truck project in accordance with the construction requirements of the East extension Line of Chengdu Metro Line 2. In this paper, the optimization of the driving system control algorithm and the design reliability of the truck are studied. Take the expectation for the subsequent improvement model as the reference design. First of all, there are many factors to be considered in the development and design of beam conveyer. We focus on the design and study of the main actuators, hoists and steering actuators of the vehicles. On the other hand, in the design and research of hydraulic system, the scheme selection of electro-hydraulic drive system, the selection and design of hydraulic components of driving system, and the control mode of the selected hydraulic components are studied. Secondly, based on the research of the driving system of the beam conveyer, the mathematical model of the driving system of the truck is established. On the one hand, the energy-saving control of the driving system of the vehicle is studied from the power matching strategy of the driving system. On the other hand, starting with the control strategy of the pump controlled motor drive system, the superiority of the new adaptive control algorithm is put forward, which provides a research idea for the drive control optimization of the truck in the future. Thus, the reliability of beam conveyer is further improved. Finally, the reliability of the whole vehicle is studied. The reliability block diagram of the driving system, steering system and suspension system of beam conveyer is established. At the same time, the reliability prediction simulation of each part of hydraulic system is carried out through the reliability mathematical model of each part. The test of steering system and driving system is verified by field test. Finally, combined with the steering system problems encountered in the debugging test, the fault tree model of the whole vehicle is established, and the grey correlation theory is innovatively used to locate the fault of the truck quickly, thus reducing the time wasted in finding the fault.
