  • COLLABORATIVE TESTING SYSTEM FOR ELASTIC WAVE AND TENSILE DAMAGE OF ROCK
    Publication number: 20240068917
    Abstract: An integrated acoustic detection and rock direct tensile test machine includes a support frame. A top of the support frame is provided with a top plate and a bearing plate is provided above the top plate. The bearing plate is provided with force transferring rods, lower ends of which are provided with a tensile base. A top of the tensile base is provided with a lower clamp holder and a bottom of the top plate is provided with an upper clamp holder. An upper channel is provided inside the upper clamp holder. The upper channel is provided with an acoustic transmitting probe. A lower channel is provided inside the lower clamp holder. One end of the lower channel is communicated with the outside, the other end is provided with an acoustic receiving probe. The lower channel extends to a bottom of a clamping chamber of the lower clamp holder.

  • ROCK TENSILE DAMAGE TESTING SYSTEM COUPLED WITH COMPLEX LOADING CONDITION
    Publication number: 20240068919
    Abstract: A rock direct tensile test platform suitable for all material test machines includes a support frame. A top of the support frame is fixed with a top plate, and a bearing plate is provided above the top plate. The bearing plate is provided with a plurality of vertical force transferring rods. The force transferring rods vertically penetrate through the top plate and have a sliding fit with the top plate. Lower ends of the force transferring rods are provided with a tensile base. A top of the tensile base is provided with a lower clamp holder. A bottom of the top plate is provided with an upper clamp holder, and a clamp center of the upper clamp holder coincides with a clamp center of the lower clamp holder.
