Abstract

The invention relates to the field of testing devices, and discloses a discrete material shearing device which comprises a shearing box, a first driving mechanism, a second driving mechanism and a third driving mechanism, the shearing box is provided with an upper box body and a lower box body which are connected in a sliding mode, and the top of the upper box body is connected with the first driving mechanism; the left side of the upper box body is connected with a second driving mechanism, and the right side of the lower box body is connected with a third driving mechanism, so that the shear box bears acting force in multiple directions. The device has the beneficial effects that a sand sample for an experiment can be accommodated in the shearing box, dynamic shearing in three directions is realized through cooperation of the first driving mechanism, the second driving mechanism and the third driving mechanism, the engineering problem of foundation shearing damage caused by dynamic loads such as earthquakes and wave impact is simulated more accurately, and the experiment efficiency is improved. And different discrete material shearing scenes can be better restored.

Description

technical field [0001] The invention relates to the field of testing devices, in particular to a bulk material shearing device. Background technique [0002] Disperse materials include soil, sand and other substances with similar properties. Disperse mechanics is a discipline that studies the limit equilibrium and motion law of a particle aggregate under force. Among them, the soil direct shearing device is a very common bulk mechanical test device. The existing soil direct shearing device can only load a certain constant load, which is inconsistent with the changing load in engineering practice, and has low precision, resulting in It cannot be well applied in practical engineering, and cannot accurately simulate engineering problems such as foundation shear damage caused by dynamic loads such as earthquakes and wave impacts. Therefore, a new type of bulk material shearing device is urgently needed to solve the above-mentioned problems. question. SUMMARY OF THE INVENTION ...
