大行程压力试验机的系统研制与应用

Development of the big trip compression testing machine

介绍了自行设计的大行程压力试验机的机械结构、工作原理、测试系统的技术方案及其在塑料检查井剪切试验与荷载试验中的应用.它能有效地解决传统压力试验机试验空间小,调整慢,试验效率低,对大试样压力测量抗偏置能力差、误差大的问题.

This study introduces the structure and control systems of the big trip compression testing machines, and its shearing and load tests in plastics inspection chambers, The purpose is to improve the ex- isting compression testing machines with regard to the smaller test trips,lower efficiency and higher error in the measurement.
