A uniaxial static compression device for detecting crack direction of complex structure of brittle material

Abstract

The application discloses a kind of detection fragile material complex structure crack direction uniaxial static compression device, comprising: support base, displacement platform, gap adjusting ring assembly, intelligent micro contact mechanism, support plate and static crushing mechanism, the top middle of support base is set telescopic mechanism;The bottom of displacement platform is connected with telescopic mechanism;Gap adjusting ring assembly is set above displacement platform;Intelligent micro contact mechanism is spaced apart and set on gap adjusting ring assembly along circumference;The both ends of support plate are connected with support base by guide column;Static crushing mechanism passes through support plate and is matched with gap adjusting ring assembly.The application carries out gap adjustment by static crushing mechanism, satisfies the dynamic crushing behavior test of different sizes of hard particles to be measured;Spring and micro induction cone are connected to accept the force of device tip, the change of real-time crack of structure is observed macroscopically, and it is transmitted to data acquisition module for recording and analysis by Hall effect sensor.
