Description

Technical field [0001] The invention relates to a structural deformation measurement technology, in particular to a dynamic ablation measurement device and a measurement method for applying an impact load on-line. Background technique [0002] The engine is the core component of an aircraft, and it is one of the decisive factors for aircraft maneuverability, range, reliability, economy and environmental impact. The aero-engine service environment is harsh and the factors are complex, and the material's response to the environment has a coupling effect, rather than a superposition of the results of a single environment. For this reason, various countries have made the environmental performance simulation of materials the main content in the corresponding major material research plans, such as the composite material plan for aircraft formulated by the United States in 1988, and the advanced thermomechanical ceramic technology jointly developed by NASA, DOE and DoD in 1990. The pla...

Problems solved by technology

For the simulation of the impact load that the material may be subjected to in the actual working condition, due to the complexity of the ablation test itself and the difficulty in building the experimental platform, so far no impact load has been considered on the material under the ablation condition, which is different from the There are obvious gaps in the actual working conditions of the material, so it is impossible to simulate and describe the response of the material in the real working environment more accurately
