【摘要】：把持力和抗弯强度是金属胎体的主要力学性能。虽然目前有较多的计算方法可以计算出胎体的理论包镶力和抗弯强度,但是与实际值相比,仍然存在误差。设计了一个金刚石胎体力学性能的智能检测装置。该装置采用压力传感器和位移传感器作为数据检测传感器,检测不同温度下试件的最高承受压力和加载速度。同时,通过数显表显示微处理后的数据并与计算机通信,用LabVIEW软件编程,实时显示数据曲线并对胎体的力学性能进行分析。现场测试表明:本仪器与万能试验机平均强度相差19.36MPa,2.16%,差值较小。最后,对装置的功能进行了总结并分析了不足之处。
[Abstract]:The holding force and bending strength is the main mechanical properties of metal matrix. Although the current method of calculating more can calculate the matrix theory of embedding capacity and flexural strength, but compared with the actual value, the error still exists. The design of intelligent inspection a diamond matrix mechanical properties measuring device. The device uses pressure sensor as a data detection sensor and displacement sensor, detection under different temperature of specimen under pressure and maximum loading speed. At the same time, through the digital display micro data and communication with the computer, using LabVIEW software programming, real time display data curve and analyze the mechanical properties of the matrix. The field test shows that this instrument and universal testing machine the average intensity is 19.36MPa and 2.16% smaller difference. Finally, the performance of the device are summarized and analyzed the shortcomings.
