摘要

摘要: 针对典型航空发动机涡轮机匣防叶片刮磨的蜂窝材料，阐述了常用的蜂窝等效模型和J-C(Johnson-Cook)模型，将两种材料模型应用于蜂窝冲击试验的仿真分析，并与试验结果进行了对比.结果表明，通过合理的参数标定及简化假设，J-C模型可提供满意的仿真结果，其中蜂窝损伤预测与试验结果很好地吻合.鉴于其使用相对简单，同时能够提供足够的预测精度，在航空发动机叶片与蜂窝的刮磨仿真分析工程应用中值得推荐.

Abstract: For typical honeycomb materials used in turbine casings of aero-engines to prevent blades from scraping the casing, 2 commonly used material models, the Johnson-Cook model and the honeycomb equivalent model, and the relevant calibration methods were discussed. Then the 2 models were implemented in the simulation of a honeycomb impact test, and the simulation results were compared with the test results. It is shown that, through appropriate parameter calibrations and reasonable simplifications, the Johnson-Cook model provides satisfying results, in which the damage prediction is in good agreement with the test observation. Since the Johnson-Cook model is relatively easier to be implemented with enough prediction accuracy, it is recommended for blade-honeycomb scraping analysis of aero-engines.
