【摘要】：本论文基于与公司的实际项目,燕山大学赵静一教授科研团队与北京百善重工有限公司针对成都地铁二号线东延线的施工要求,合作开发的重型载重运输车项目。本文主要是对载重运输车的驱动系统控制算法优化以及整车的设计可靠性方面进行了研究。以期望为后续的改进车型作参考设计。首先,在运梁车的开发设计过程中考虑的因素很多,我们重点对运梁车的主要执行机构,悬挂升降机构和转向执行机构进行了设计研究。另一方面在液压系统的设计研究中,主要对电液驱动系统的方案选定,驱动系统液压元件的选型设计,以及所选液压元件的控制方式进行了研究。其次,基于运梁车驱动系统的研究,通过建立载重运输车驱动系统的数学模型,一方面是从驱动系统的功率匹配策略研究了运梁车驱动系统的节能控制;另一方面从泵控马达驱动系统的控制策略入手,提出了新的自适应控制算法的优越性,为今后载重运输车的驱动控制优化提供了研究思路。从而进一步提高了运梁车的可靠性。最后,对运梁车的整车进行了可靠性研究。主要对运梁车的驱动系统,转向系统,悬挂系统,建立了可靠性框图,同时也通过各个部分的可靠性数学模型,对液压系统的各个部分进行了可靠度预测仿真。并结合现场的调试试验,重点对转向系统和驱动系统的测试进行了验证说明。最后结合调试试验时遇到的转向系统问题,通过建立了运梁车整车的故障树模型,创新性的运用灰关联理论,快速定位载重运输车的故障,减少了寻找故障所浪费的时间。
[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.
