基于虚拟仪器的液压CAT系统设计与研究

Research of Hydraulic Computer Aided Test(CAT)System Based on Virtual Instruments

虚拟仪器是计算机技术在仪表领域中应用所形成的一种新型的、富有生命力的仪器种类。本文以液压综合实验台为基础,应用虚拟仪器技术设计了液压CAT系统最经济、可靠的方案,采用功能强大的开发工具VB6.0编制应用软件,实现了对液压泵、液压马达、液压油缸和各种阀类液压元件以及双弹车液压系统的自动测试。该系统在某厂的液压综合实验台上调试成功,取得了较好的效果。

Virtual Instrument is a new and vivid kind of instruments created by using computer-technique in the field of apparatus.This paper discusses the disign of a set of hydraulic CAT system which is based on virtual instrument and applied to the hydraulic test-bed.Applications of hydraulic CAT system is programmed by a very strong program tools-VB6.0.Automatic test of hydraulic pump,motor,jack and all kinds of valve has been realized by this system.It has been applied to a hydraulic test-bed of one factory sucessfully.
