Abstract

The invention discloses a device and method for measuring the liquid flow-solid conversion mechanism in an impact process. The device comprises a pressure box body and a loading tank arranged in the pressure box body, wherein an air valve is arranged on the pressure box body; a loading rack is also arranged in the pressure box body; the loading tank is arranged in the loading rack; an impact device connected with a motor power device and ascending and descending on the loading rack is arranged at the upper end of the loading rack; the lower end of the impact device is connected with an impact object which can acts on the loading tank; a speed measuring sensor is arranged on the impact object; pressure sensors are arranged at the bottom and on the side surfaces of the loading tank; a video capture instrument and a particle dynamics scanner are arranged on the loading rack; a stop block is further arranged on the loading rack and positioned right below the impact device. According to the invention, the liquid flow-solid conversion critical speed in the impact process can be well measured, different formulas can be evaluated and the matching can be optimized.

Description

technical field [0001] The present invention is capable of studying the basic mechanical behavior of the granular material in the solid-liquid transformation process through the impact test, understanding the contribution rate of shear flow and extrusion flow in the solid-liquid transformation process, and revealing the internal mechanism of the solid-liquid transformation. So as to provide guidance for practical engineering applications, it is widely used in many technical fields such as chemical industry, textile, transportation, civil engineering, medical treatment, and national defense. Background technique [0002] The transition phenomenon between solid and liquid phases of particulate matter widely exists in many fields such as engineering geology, natural environment, industrial production and national defense construction, and its mechanical properties will change greatly during the phase transition process. Research hotspots and difficulties. The solid-liquid tran...
