The invention discloses a similar material
simulation test
system and relates to an apparatus for measuring or testing force, stress and displacement, in particular to a test
system for laboratories to simulate and monitor support load and displacement changes by the aid of similar materials during
coal bed excavation. The similar material
simulation test
system is capable of obtaining real-
time pressure and displacement of a support when the support interacts with surrounding rocks. The similar material
simulation test system comprises a model support 1, at least one movable column 2, pistons 21, vertical columns 3, a first measuring cylinder 5, a second measuring cylinder 6, a radio-frequency capacitive liquid level
transmitter 8 and a radio-frequency capacitive liquid level
transmitter 9. The insides of the vertical columns 3 are mutually communicated to form a liquid accommodating cavity 4, liquid is arranged in the liquid accommodating cavity, the first measuring cylinder and the second measuring cylinder are higher than the pistons, a connecting tube 7 is communicated between the first measuring cylinder and the second measuring cylinder through side walls of the first measuring cylinder and the second measuring cylinder, the lower end of the first measuring cylinder is communicated with the liquid accommodating cavity 4 through a hose 41, and the two radio-frequency capacitive liquid level
transmitter 8 and 9 are used for measuring the liquid level inside the two measuring cylinders.
