【摘要】：滑移装载机是一种实用性很强的小型工程机械，由于作业效率高、机动性能好、功能多样化而广泛地应用于各行各业。工作装置及其液压系统是滑移装载机的重要组成部分，其性能决定了整机的工作性能，因此研究其具有重要意义。以往的研究多是基于数学模型进行理论分析，对相关因素进行了简化等效，从而不能准确反映系统的实际性能。为此，本文结合校企合作项目，基于仿真软件准确建立工作装置及其液压系统的仿真模型并结合实验测试，进而更好地对工作系统的性能进行分析研究。本文首先对滑移装载机的相关情况及其工作装置进行了介绍，详细分析了工作液压系统特别是调平系统的工作原理，同时对调平运动进行了分析计算。在此基础上，基于AMESim仿真软件建立了工作液压系统各元件的模型及系统的模型，同时通过机构库中元件建立了工作机构的模型，从而更好地体现工作装置动作过程中的受力情况。通过不同工况的仿真，分析了工作系统的性能。通过实验与仿真的对比分析，验证了仿真模型的正确性，并分析了负载、发动机等因素对系统性能的影响，进而更好地分析了系统的性能。论文通过对滑移装载机工作装置及其液压系统的分析，，为滑移装载机液压系统的改进提供了可借鉴的方法，同时也可应用在其他工程机械车辆工作系统的设计与改进中。
[Abstract]:Slip loader is a kind of small engineering machinery with strong practicability, because of its high working efficiency and good maneuverability. The working device and its hydraulic system are important parts of the slip loader, and its performance determines the working performance of the whole machine. Therefore, it is of great significance to study it. Most of the previous studies are based on mathematical models for theoretical analysis, and the related factors are simplified and equivalent, which can not accurately reflect the actual performance of the system. In this paper, the simulation model of the working device and its hydraulic system is established based on the simulation software, and the performance of the working system is analyzed and studied. This paper first introduces the relevant situation of slip loader and its working device, and analyzes in detail the working principle of hydraulic system, especially the leveling system. At the same time, the flattening motion is analyzed and calculated. On this basis, based on the AMESim simulation software, the model of each component of the hydraulic system and the model of the system are established. At the same time, the model of the working mechanism is established through the components in the mechanism library, so as to better reflect the force situation in the course of the working device action, and through the simulation of different working conditions. The performance of the working system is analyzed. The correctness of the simulation model is verified by comparing the experiment and simulation, and the influence of load, engine and other factors on the performance of the system is analyzed. Furthermore, the performance of the system is analyzed better. Through the analysis of the working device and hydraulic system of the slip loader, the paper provides a reference method for the improvement of the hydraulic system of the slip loader. At the same time, it can also be used in the design and improvement of the working system of other construction machinery vehicles.
