新型抗折试验机控制系统的设计

Design and Implementation a New Type of Control System for Testing Antifracture Machine

为了在等载荷加载过程中测试金属材料及其合金材料室温状态的最大抗折强度,笔者运用单片机技术、传感器技术、计算机技术、点阵图形液晶及交流电机伺服控制等技术,开发了一套新型抗折试验机的控制系统。以手动或自动控制两种方式完成伺服电机的控制,实现了材料断裂试验的全过程。使用结果表明:新型抗折试验机控制系统达到了高精度材料试验的要求,具有可靠性高、成本低、使用方便和维护性好等优点,满足了工程需要。

In order to realize the control of testing progress for the largest intensity of all kinds of materials in the state of equal load, a new kind of control system for testing antifracture machine was presented. The system was developed by means of the technologies of electron, computer, single- chip microcomputer, servo system, communication and digital signal processing. It can realize the auto controlling or manual test controller etc. The application result shows that control system for testing antifracture machine can meet the require of high precision materials testing, has high stability and reliability.
