一、前言液压元件性能的高精度测试是发展液压技术,提高液压元件性能的重要手段之一。在液压元件的设计、制造、改进中都需要进行大量的、高精度的测试工作,以深刻认识元件的性能并作出分析对比。计算机辅助测试(CAT)在提高测试精度、测试速度、测试的重复性和可靠性,从而在节省大量人力和能源方面都提供了必要的保证,因此在国内外都受到了普遍重视。但是液压元件CAT涉及到试验方法、测试用的各种传感器和仪表,计算机的硬元件
I. Introduction The high-precision testing of hydraulic components performance is one of the important means to develop hydraulic technology and improve the performance of hydraulic components. In the design, manufacture and improvement of hydraulic components, a large amount of high-precision test work needs to be carried out to deeply understand the performance of the components and make an analysis and comparison. Computer Assisted Testing (CAT) is gaining widespread recognition both at home and abroad because it provides the necessary assurances in terms of improving test accuracy, test speed, test repeatability and reliability, saving a lot of manpower and energy. However, hydraulic components CAT relates to test methods, various sensors and meters for testing, hard components of computers
