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 cantilever centrifugal high-gravity 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. Security 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 and c...
