Temperature-controlled static-dynamic triaxial test device based on MTS power source

Abstract

The invention discloses a temperature-controlled static-dynamic triaxial test device based on an MTS power source. The test device comprises an MTS test machine, a high-and-low-temperature environment box and a triaxial test system. The MTS test machine provides an acting force required by the test; and the high-and-low-temperature environment box provides the temperature required by the test. The triaxial test device includes a pressure chamber, a measuring system, and a confining pressure system. The confining pressure system provides a stable confining pressure in high-low ranges for a test sample; the test temperature is controlled accurately by setting the temperature parameter of the high-and-low-temperature environment box; and various static and dynamic loads are controlled by a computer, so that the high-and-low-temperature static-dynamic triaxial test study on various civil engineering materials is performed. The mechanical properties of materials, especially the materials with high temperature sensitivity in different temperature environments can be reflected truly. According to the invention, the temperature-controlled static-dynamic triaxial test device has advantages of reasonable structure, great convenience in usage, and high efficiency; and static-dynamic triaxial tests at different control temperatures and under different stable confining pressures can be carried out successfully. The temperature-controlled static-dynamic triaxial test device is suitable for testing of various materials.

Description

technical field [0001] The invention relates to the field of civil engineering experiment equipment, in particular to a temperature-controlled static and dynamic triaxial test device based on an MTS power source. Background technique [0002] At present, when most scientific research institutes conduct static and dynamic triaxial tests on various geotechnical materials, it is difficult to accurately control the temperature during the test process. Most of the tests were carried out at temperatures above freezing, however the applicability of these findings is questionable when the material is located in severe cold regions. Especially for materials that are sensitive to temperature changes, such as soil and asphalt concrete, their mechanical properties vary greatly between low temperature and normal temperature. In addition, at present, static and dynamic triaxial tests of geotechnical materials are generally carried out separately on static triaxial instruments and dynamic...
