本文主要介绍飞机鸟撞试验有限元三维仿真模型的建立及有限元分析的方法,模型仿真计算结果与试验结果相比较,具有良好的一致性,从而验证了此分析方法的分析结果是具有一定的参考价值。可降低直接通过试验确定鸟体参数的困难度及高成本。
This paper mainly introduces the establishment of the three-dimensional finite element simulation model of aircraft bird-bump test and the method of finite element analysis. The calculated results are in good agreement with the experimental results, which verifies that the analysis results of this method are of certain Reference value. Reducing the difficulty and cost of determining bird parameters directly through experiments.
