Embodiment Construction

[0026] The invention is a dynamic three-axis testing machine driven by an electric cylinder servo, and its structure includes a main body and a control part. The main body includes the confining pressure loading part and the pore water pressure part, which are the core of applying load to the sample; the confining pressure loading part applies surrounding pressure to the sample through the air source, and the vertical static load and vertical dynamic load pass through the servo electric cylinder The reciprocating motion of the sample loads the sample; the pore water pressure is partly connected to the pressure sensor of the drain pipe of the sample base for measurement. The control part and the main part work in unison and coordinate to jointly realize the detection purpose of the device of the present invention.

[0027] refer to figure 1 , the structure of the device of the present invention is that a pressure chamber base 1 is fixedly installed on the table of the mobile t...

Abstract

The invention discloses a dynamic triaxial testing machine servo-driven by an electric cylinder. According to the dynamic triaxial testing machine, a pressure chamber base is upwards connected with a pressure chamber top cover, and a pressure cavity is formed by a side wall cylindrical shell between the pressure chamber top cover and the pressure chamber base. A side direction measuring mechanism is installed on an inner steel column of an inner cavity of the pressure cavity. The pressure chamber base is provided with the servo electric cylinder, a vertical displacement sensor is arranged at the lower end of the servo electric cylinder, the upper end of the servo electric cylinder is connected with a sample base through a lead screw, a rubber membrane is disposed on the sample base, a pore water pressure sensor is mounted in a sample drainage pipe of the sample base, and a confining pressure sensor is installed in an air source passage of the pressure cavity. A sample cap is arranged on the upper end face of the rubber membrane. The sample cap is upwards connected with a vertical force transmission shaft, and an axial pressure sensor is installed on an axial force transmission rod. The dynamic triaxial testing machine resolves the problems that occupied area is large, noise is high, pollution is heavy and accuracy is not high enough in the prior art.

Description

technical field [0001] The invention belongs to the technical field of geotechnical engineering testing equipment, and relates to a dynamic three-axis testing machine driven by an electric cylinder servo. Background technique [0002] In addition to static loads, geotechnical structures and their foundations are sometimes subjected to dynamic loads, such as seismic loads caused by earthquakes, vibration loads caused by vehicle and machine vibrations, and knock loads caused by explosions. Relatively speaking, the static load and the magnitude and direction of action of the static stress caused in the soil do not change with the time of action, while the direction of action of the dynamic load and the magnitude of the dynamic stress caused in the soil changes with the action time. change over time. Some of these changes are random waves, such as the seismic stress caused by an earthquake; some are similar to sine waves, such as the vibration caused by a reciprocating machine;...
