Soil dynamic triaxial testing system

Microcomputer controlled electro-hydraulic servo soil dynamic triaxial testing machine

1. Application
Microcomputer controlled electro-hydraulic servo soil dynamic triaxial testing machine is mainly used for axial testing of rocks, sand and magma. Strength tests of pressure and lateral pressure, soil dynamics tests, are also used to determine the total, shear strength and effective shear strength parameters of fine-grained soils and sandy soils. According to different drainage conditions, the following tests should be completed:
, unconsolidated undrained shear test
, consolidated undrained shear test
, and consolidated drained shear test.
This dynamic three-axis testing machine adopts Lichuang's fully digital microcomputer-controlled electro-hydraulic servo multi-channel control system (r system). This system is a fully digital microcomputer that has been carefully developed by Lichuang's engineering and technical personnel for many years. Control electro-hydraulic servo multi-channel test control system (r), one of the series products, has been protected by the patent technology (patent number:) of the State Intellectual Property Office. It is the independent knowledge obtained by our country's engineering and technical personnel in the field of large-scale high-precision test technology. One of a series of proprietary test controllers. It is widely used in the real-time control of multi-axis dynamic tests of key large-scale test projects in scientific research institutes such as the Institute of Mechanics of the Chinese Academy of Sciences, Ocean University of China, and the Academy of Hydraulic Sciences of the Yellow River Water Conservancy Commission.
