A material performance testing system is installed in the hanging cup, the hanging cup is provided with a heat preservation device, the heat preservation device is provided with a heating device, the heating device is provided with a force bearing device, and the hanging cup is hinged to the end of a rotating arm of the supergravity centrifugal machine through a lifting lug. According to the invention, high-throughput testing of material properties such as durability, creep deformation, fatigue and the like in a centrifugalsupergravity environment is realized, and a uniform stress gradient, a non-uniform stress gradient, a uniform temperature field and a non-uniform temperature field can be applied to a sample so as tosimulate the working condition environment of the sample to the greatest extent.

Description

technical field [0001] The invention relates to a high-gravity material performance testing machine in the technical field of material performance testing, in particular to a material performance testing machine system in a centrifugal force-high temperature coupling environment. Background technique [0002] Blade machinery is key equipment in the aerospace, metallurgy, and energy industries, such as aero-engines, compressors, steam turbines, water turbines, etc. The design, operation, and maintenance of this type of machinery are related to the safety and stability of major engineering projects. Safety is of great importance. [0003] Turbine working blades, as the core components of aero-engine high-temperature gas work, are usually designed as geometric structures with variable cross-section, strong torsion (twist over 60 degrees), thin-walled curved surface (the thinnest part of the edge is less than 3mm), and complex topological shapes. The special geometric structure...
