Abstract

The present invention relates to the technical field of triaxial test devices, and relates in particular to a voltage stabilisation mechanism, a mechanical rheological experiment system, and a test method therefor. The voltage stabilisation mechanism comprises a press rod and a piston, an end portion of the piston being slidably arranged on the press rod, one end of the press rod being provided with a base hinge portion to implement vertical rotation of the press rod, the other end of the press rod being provided with a force application portion. The voltage stabilisation mechanism has a simple structure, is quick and easy to operate, can avoid the disadvantages caused by implementing voltage stabilisation via electric control, and ensures loading force stability. In addition, the mechanical rheological experiment system which uses the voltage stabilisation mechanism can eliminate the problem of loading force instability caused by voltage instability during traditional electric control, so that test results are more stable and accurate, and can be applied to various triaxial tests.
