Product Description
There are two loading methods: uploading and downloading
1. Purpose and scope of application
The purpose of this test is to determine the elastic modulus of saturated soil, soil samples or the stress, strain and pore water pressure change process of samples mixed with cement, gravel or soil under dynamic action, so as to determine its failure strength under dynamic action ( Including liquefaction), dynamic characteristic indicators such as dynamic modulus and damping ratio when the strain is greater than 10-4 (. Large elastic modulus).
2. The composition of the instrument
The instrument is an electromagnetic servo vibration three-axis. Its composition includes main engine, electro-hydraulic servo control system, pressure control system, computer control, data acquisition and software processing system and other components.
(1) Host: including pressure chamber, servo electric cylinder.
(2) Electromagnetic servo control system: used for axial vibration, applying axial dynamic stress, and controlling servo electric cylinder.
(3) Pressure control system: apply confining pressure, back pressure, including pipeline, air source, water source, etc.
(4) Computer control, data acquisition and software processing system: The computer controls the whole process, collects and records the whole process of the test in real time, and automatically generates test record sheets and curve reports after the test is completed.

(6) Servo control system
The servo control system is a new generation of intelligent measurement and control products developed based on the ISD platform. It is a built-in microcomputer PCI2.1 specification measurement and control card with a built-in 32-bit floating-point DSP control core and a DTE embedded real-time operating system to achieve any multi-channel closed-loop control. The measurement and control frequency of 10,000 times/second can meet the high standard measurement and control requirements of the dynamic test specification.
