Abstract

The invention discloses a text piece mass measurement device for a triaxial experimental apparatus. The text piece mass measurement device comprises a triaxial experiment loading system and a triaxialapparatus stress chamber for placing a test piece, and further comprises a mass detection unit for detecting a mass of the test piece and converting a mass signal of the test piece into an electric signal, and a mass output unit for outputting mass information, wherein the mass detection unit is arranged at the bottom of the triaxial apparatus stress chamber, and the mass detection unit outputs adetection result to the mass output unit. The text piece mass measurement device for the triaxial experimental apparatus can replace a conventional balance measurement mode to measure the masses of the test piece before and after a triaxial experiment, so that the test piece measurement accuracy is greatly improved, and a step of manually measuring the mass of the test piece is eliminated; the operation is simple and convenient, and the experimental efficiency is improved.

Description

technical field [0001] The invention relates to a triaxial experimental instrument, in particular to a test piece quality measuring device for a triaxial experimental instrument. Background technique [0002] The triaxial tester (also known as the triaxial testing machine) is a commonly used test instrument in the laboratory. It applies an axial sample force to the test piece through the axial system, applies a confining pressure to the test piece through the pressure chamber, and simultaneously passes the temperature The control system makes the upper and lower end surfaces of the test piece and the middle part of the test piece respectively in different temperature environments, thereby simulating various actual working conditions such as freezing and thawing of the test piece. In the triaxial test of the specimen, the mass loss rate of the specimen is sometimes a quantity that needs to be observed. Generally, the method of measuring the mass loss rate is to divide the mas...
