Description

technical field [0001] The invention relates to an ablation test device and method for applying load online, and belongs to the technical fields of engineering materials, structural deformation and mechanical experiments. Background technique [0002] The engine is the core component of the aircraft and one of the decisive factors affecting the performance of the aircraft. The working environment of the engine is harsh and the actual working conditions are complex. There is a coupling effect in the response of engine materials and structural parts to the environment. The working conditions have a force-heat-fluid-solid coupling effect, rather than a simple superposition of a single factor. For this reason, in the corresponding major material research plans of various countries, the environmental performance simulation of materials is taken as the main content, such as the aircraft composite material plan formulated by the United States in 1988, and the advanced thermal engin...

AI Technical Summary

Problems solved by technology

For the environment and material simulation of engine structural materials, most of the current research is still focused on the physical and chemical properties of the material itself, and the assessment of the properties of the material is mainly focused on the ablation experiment, while the coupling effect of the environment during the ablation process Simulation doesn't take much into account

Especially for the simulation of the force load under the actual working conditions of the material, due to the complexity of the ablation experiment itself and the difficulty of building the test bench, so far there has been no consideration of the load applied to the material under the ablation condition, which is different from the There is a significant gap in the actual working conditions of the material, so it is not possible to simulate and describe the response of the material in the real working environment more accurately
