【摘要】：起重机是现代社会工程施工中非常重要的设备之一,特别是汽车起重机,由于其具有机动性好、转移迅速、起重量范围大等优点,随着我国经济建设的飞速发展,其需求量越来越大,对其性能要求也越来越高。变幅系统作为起重机的重要子系统之一,其动态性能的好坏直接影响到整个起重机的性能。以往液压系统的设计均依靠经验和类比的方法,然后通过样机来检验设计是否合理。这样既花费了大量的时间和精力,又存在巨大的风险。通过对液压系统的仿真分析,可以在设计初期就发现不合理之处,减少设计的弯路和损失,缩短设计周期,提高效率。 本文主要对50吨汽车起重机的变幅系统进行了分析和基于AMESim软件对其进行建模仿真,对不同工况下的仿真结果进行了分析,重点对影响变幅性能的主要元件——平衡阀的相关物理量进行了分析研究,论证了其在变幅系统中的重要作用。同时,通过实验和仿真的对比分析,检验了仿真模型的准确性,进而论述了仿真技术在液压系统设计中的重要作用。
[Abstract]:Crane is one of the most important equipment in modern social engineering construction, especially automobile crane. Because of its advantages of good mobility, rapid transfer and large lifting weight, with the rapid development of economic construction in China, crane is one of the most important equipment in modern social engineering construction. Its demand is more and more large, its performance request is also more and more high. As one of the important subsystems of crane, the dynamic performance of the system directly affects the performance of the whole crane. In the past, the design of hydraulic system depended on experience and analogy, and then the prototype was used to verify whether the design was reasonable or not. This not only cost a lot of time and energy, but also a huge risk. Through the simulation analysis of hydraulic system, the unreasonable points can be found at the beginning of design, which can reduce the curve and loss of design, shorten the design cycle and improve the efficiency. In this paper, the amplitude change system of 50 ton truck crane is analyzed and modeled based on AMESim software, and the simulation results under different working conditions are analyzed. The related physical quantities of the balance valve, which is the main component affecting the amplitude change performance, are analyzed and studied, and its important role in the amplitude change system is demonstrated. At the same time, the accuracy of the simulation model is tested through the contrast analysis between the experiment and the simulation, and the important role of the simulation technology in the hydraulic system design is discussed.
