Description

technical field [0001] The invention relates to the technical field of rock dynamic physical and mechanical measurement, in particular to a device for simulating the dynamic friction process of original rock and a manufacturing method thereof. Background technique [0002] The formation and development of earthquakes are closely related to the frictional sliding of plates. Frictional sliding is accompanied by complex processes such as plate strength reduction, plate breaking, massive energy release, and changes in the original performance of plates due to energy release. Plate friction also has Very complex properties, frictional properties affect the propagation of high-amplitude seismic waves through rock fractures and faults. The study of plate dynamic friction during earthquakes has become one of the main ways to reveal the law of earthquake development. Laboratory studies show that frictional properties can be measured in active seismic surveys. [0003] The nature of...

Problems solved by technology

Recently, the method of Kolski rod has been used to measure the kinetic friction coefficient between steel and aluminum, however this method is not suitable for rock-like materials

[0004] At present, the dynamic friction test mainly uses two independent samples to realize the dynamic friction process by means of a special experimental device. The experimental device is complicated, and the secondary processing of the sample loses the originality of the friction test; Experimental research under additional conditions (such as temperature, pressure, loading rate, etc.) is not easy to achieve; dynamic friction phenomena cannot be fully described
