Abstract

The paper introduces a detection system of local mechanical strength of material. The principle of the system is based on the double-hole micro-shear test method. The core of detection system is MSP430F149 SCM. The working principle of the system is that the shear tool is driven by the stepper motor; the data is gathered by the load sensor and the displacement sensor; after it is processed by A/D converter of MSP430F149 SCM, we can gain the load and the displacement curve and get the maximum point of yield strength; according to the load value, the system determines the material mechanical intensity; Thus, a real-time detection system is set up. Experimental results show that detecting system based on double-hole micro-shear is fast, easy, accurate and intuitive to detect mechanical strength of the local material. So it can be widely applied to detect the local mechanical strength of kinds of mining and load bearing equipment via setting reasonable load value, which can avoid the accident of overload or super strength effectively.
