At present, mechanical tests of explosives and solid propellants under confining pressure are limited to passive confining pressure samples, namely a metal sleeve is sleeved on the surface of a sample to perform a uniaxial compression test, and the confining pressure is obtained by performing reverse thrust through the surface deformation of the metal sleeve. On one hand, the method cannot accurately obtain the confining pressure, on the other hand, the confining pressure is continuously increased in the loading process, and the confining pressure is difficult to artificially control, so that an active confining pressure tensile compression test method for explosives and solid propellants is urgently needed to be developed.

And data such as confining pressure, axial load, deformation, temperature and the like are checked and recorded in real time through a human-computer interaction system.
