CAT系统与常规测试系统相比,具有精确、能自动进行后续数据处理、便于探讨机械的设计机理以及易于揭示内在问题等优点。本文以APPLE-Ⅱ微型计算机为核心,并配备磁带记录仪、信号处理仪、数字绘图机和相应接口电路的CAT系统。同时,针对折弯机的同步系统,说明CAT的应用方法及其对提高机械产品质量所起的作用。一、待测机械系统与测试目的图1是一种现代液压板料折弯机的示意图。这种折弯机由左、右两油缸推动滑块和
Compared with the conventional test system, the CAT system has the advantages of being accurate and capable of automatic follow-up data processing, facilitating the discussion of the mechanical design mechanism and easy revealing of inherent problems. In this paper, APPLE-Ⅱ microcomputer as the core, and equipped with tape recorders, signal processors, digital plotter and the corresponding interface circuit CAT system. At the same time, for the bending machine synchronization system, explain the application of CAT and its role in improving the quality of mechanical products. First, the test mechanical system and test purposes Figure 1 is a schematic view of a modern hydraulic sheet metal bending machine. This bending machine by the left and right two cylinders to promote the slider and
