【摘要】：液压传动系统具有结构轻巧、传动比大、运行平稳、易于实现无级调速和自动控制等优点,已被广泛应用于工业生产中的各个领域。《液压传动》是我国高校机械相关专业的一门重要专业基础课,在高校的液压传动教学中,实验教学是其中的一个重要环节。随着学校招生规模的扩大,各学校普遍出现学生多、仪器少,且仪器设备相对落后的实验现状。因此,如何在减少成本投入但又能较大改善目前液压传动实验教学相对落后现状的相关课题就出现了。本文采用虚拟仪器技术,以Lab VIEW这一软件为开发平台,设计了一套包含液压传动实验教学所要求的几类典型实验模块的液压综合实验系统。本文主要包括以下几个方面的内容：一、简要介绍虚拟仪器技术出现的背景、特点及其研究现状；以及Lab VIEW的发展历程和发展前景；二、简要介绍了高校目前液压传动实验开展的状况、基本原理和各类典型实验所包含的实验内容；三、根据液压传动各典型实验的实验原理,分别从硬件和软件两方面对虚拟液压综合实验系统进行了设计；四、利用现有条件对所设计的液压综合实验系统中的性能部分进行了相应的验证。通过实验验证,从所得实验数据和各类曲线可知,该系统具有较高的精度和实用性,为高校的液压传动实验的开展提供了较好的平台。同时根据实际实验需要,可以在本系统的基础上进行功能的扩展以适应更广泛的实际需要。
[Abstract]:Hydraulic transmission system has the advantages of light structure, large transmission ratio, stable operation, easy to realize stepless speed regulation and automatic control, etc. Hydraulic transmission is one of the most important basic courses for mechanical related majors in colleges and universities in our country. Experimental teaching is one of the important links in hydraulic transmission teaching in colleges and universities. With the expansion of school enrollment, there are more students, fewer instruments and less equipment in various schools. Therefore, how to reduce the cost but can greatly improve the current hydraulic transmission experimental teaching relatively backward status of the relevant issues. In this paper, using virtual instrument technology and Lab VIEW software as the development platform, a hydraulic comprehensive experimental system including several typical experimental modules required by hydraulic transmission experimental teaching is designed. This paper mainly includes the following aspects: The main contents are as follows: 1. The background, characteristics and research status of virtual instrument technology are briefly introduced, as well as the development course and prospect of Lab VIEW. Secondly, the paper briefly introduces the status quo, basic principle and experimental contents of various typical experiments of hydraulic transmission in colleges and universities. Thirdly, according to the experimental principle of each typical experiment of hydraulic transmission, the virtual hydraulic comprehensive experimental system is designed from two aspects of hardware and software; Fourthly, the performance part of the hydraulic comprehensive experimental system is verified by the existing conditions. According to the experimental data and curves, the system has high accuracy and practicability, which provides a good platform for the development of hydraulic transmission experiments in colleges and universities. At the same time, according to the actual needs of the experiment, we can expand the function on the basis of the system to meet the needs of a wider range of practical needs.
