A New Design of Triaxial Test Chamber with Temperature and Pressure for Deep Rock

摘要

According to the research of existing triaxial testing machine of deep rock, a new test chamber with temperature-hold and pressure-tight is developed. The features of test box are as follows: a new kind of axial displacement test system with outer embedded type is designed for measuring the axial displacement of samples correctly; the circuit of oiling system is used to keep temperature and pressure; it's convenient to take down the test box from the machine and the other functions of testing machine are not affected. So the availability factor of instrument can be improved. Finally, the thickness of cylinder wall is calculated, and according to the modeling and finite element analysis based on ANSYS, the results show that the cylinder can meet the working requirement.
