Abstract

The invention relates to an axial-flow type high-flow-speed high-pressure-intensity test device, which comprises a container, a high-pressure fluid input device, a fluid output device, a fluid speed measuring device, a water pressure measuring device, a fixed shaft rod, a movable shaft rod and a compressed gas conveying device. According to the device, the dynamic mechanical property of a materialsample can be obtained by carrying out a uniaxial compression test in a high-flow-speed high-pressure-intensity fluid, so that the damaged mechanical property of the material sample in a high-flow-speed high-pressure-intensity fluid environment is analyzed.

Description

technical field [0001] The invention relates to the technical field of material mechanical performance testing, in particular to an axial-flow high-flow-velocity high-pressure testing device. Background technique [0002] The mechanical properties of materials refer to the mechanical properties exhibited by materials when subjected to various external loads (tension, compression, bending, torsion, impact, alternating stress, etc.) under different environments (temperature, medium, humidity, etc.). Understanding the mechanical properties of materials can provide a basis for selecting materials when designing various engineering structures. [0003] With the continuous development of material mechanical performance testing, the complexity of the simulated environment is becoming higher and higher. In the fluid environment, factors such as flow velocity, pressure, and mixture make the experimental research much more difficult than in the air environment. Therefore, testing the...
