Electro-Servo Control System for Thermomechanical Properties Testing

CODEN: GTJODJ

Abstract

The main features of a system for pseudo-static thermomechanical triaxial rock testing systems are discussed. The system emphasizes ease of control and versatility in performing complex load/deformation paths required in many testing applications in the temperature-pressure range of 20 to 200°C and atmospheric pressure to 70 MPa. The pressurization system, utilizing electric motor-driven pumps and a computer-aided data acquisition/motor control system is described in detail. Example results are given of the application of the test system in determination of thermoelastic properties of a quartz monzonite rock.
