AI Technical Summary
Traditional multi-parameter coupling measurement devices for coal mine dynamic disasters are not convenient for clamping coal mine specimens, leading to unstable measurements. Furthermore, rigid clamping can easily cause specimen movement or deformation, affecting the accuracy of test results.
A silicone plate clamping device with a high-pressure resistant rigid sealed shell, combined with a hydraulic rod and rotating shaft structure, is used to ensure the stability of the specimen during the test. At the same time, metal sound insulation plates and porous sound-absorbing materials are used to reduce noise and provide a stable testing environment.
This ensures that the specimen does not move or deform during the test, improving the accuracy of the test results, and provides a good testing environment through noise reduction measures.
