Abstract

The invention discloses a dynamic punching shear experimental device and experimental method. The dynamic punching shear experimental device comprises a confining pressure cylinder, an incident bar and a transmission bar. Wherein the confining pressure cylinder comprises a cylinder body, a first baffle and a second baffle opposite to the first baffle, a first hole is formed in the first baffle, a second hole is formed in the second baffle, the incident rod part penetrates through the first hole to be connected with the confining pressure cylinder, and the transmission rod part penetrates through the second hole to be connected with the confining pressure cylinder. According to the invention, the test sample is clamped between the incident rod and the transmission rod, and then the incident wave is applied to the test sample through the incident rod, that is, the dynamic load is applied to the test sample through the incident rod, so that the purpose of carrying out a punching shear experiment on the test sample is realized. In addition, the dynamic punching shear experiment device provided by the invention is also provided with a confining pressure cylinder, so that confining pressure can be applied to the sample to simulate the confining pressure borne by the sample in a natural environment, and then the dynamic punching shear experiment on the sample under the action of the confining pressure is realized, and the dynamic punching shear data of the sample can be more accurately acquired.

Description

technical field [0001] The invention relates to the technical field of dynamic mechanical testing, in particular to a dynamic punching and shearing experimental device and an experimental method. Background technique [0002] In order to ensure the safety of deep energy mining, it is necessary to study the dynamic properties of deep rocks. In the related art, in order to obtain the dynamic punching shear data of the deep rock, the dynamic punching shear experiment of the deep rock is often carried out by using the Hopkinson compression bar, so as to obtain the dynamic punching shear data of the deep rock. However, traditional Hopkinson compression bars cannot simulate the various forces that deep rocks are subjected to in the natural environment, so the dynamic punching shear data of deep rocks cannot be accurately obtained. SUMMARY OF THE INVENTION [0003] The embodiment of the invention discloses a dynamic punching and shearing experimental device and an experimental m...
