Abstract
Hydraulic transmission technology has been widely used in various industries, in particular the metallurgical field. Here the performance of the hydraulic components can guarantee the stability of hydraulic system operation and is also very important to its reliability. To identify system malfunctions and examine performance of newly-arrived and post-repair hydraulic components necessitates test equipments. At present the test-bed is mostly applied domestically to examine performance of a type or several kinds of hydraulic parts, which is far from meeting the test demand since there are wide variety of hydraulic components in the system. The development of computer software and hardware technology as well as CAT (Computer Aided Test), especially the application of VI (visual Instrument) in the automated test of hydraulic components, plays an important role in the improvement of test efficiency and precision as well as in research and development of hydraulic components and system. In the thesis, the author develops a set of comprehensive hydraulic test-bed instrument centrally controlled by CAT, which is of great significance in enlarging test scope of hydraulic components and increasing test efficiency.

摘要
摘要
液压传动技术已经广泛的应用于各种工业领域，尤其在冶金领域大量 采用了液压系统。其中液压元件性能的高低是能够稳定地运行液压系统的 保障也是维持系统可靠性的重要环节。对判别系统故障，测试新进厂的液 压元件和维修后的液压元件都需要有检测设备。目前国内使用的试验台设 备大多针对某一类型元件或几类液压元件进行性能测试，但是液压元件类 型繁多，远远不能满足测试需求。随着计算机软硬件技术和计算机辅助测 试技术的发展，特别是虚拟仪器技术在液压元件性能的自动测试中应用， 对提高测试的效率和精度、液压元件和系统的研发具有重要作用。所以本 课题研制开发了一套由计算机辅助测试系统集中控制的液压综合试验台设 备，对提高测试元件范围、测试效率具有重要的意义。
The thesis presents comprehensive analysis of experiment contents of various hydraulic components and test results for different hydraulic features. Based on Lab VIEW 8.20 program software, an all-round hydraulic test-bed used in hydraulic test system is developed. It can serve many functions, completing the performance test of hydraulic pump, hydraulic motor, hydraulic cylinder, and hydraulic valve, collecting and analyzing data, and producing test report. In addition, during the design phase of test systems, the author fully exploits the functions of the Lab VIEW 8.20 software. As a result, the design enjoys modular and hierarchical structure which improves the programming
