| 摘 要： | 本文以直升机结构试样软油箱为研究对象,对其抗坠毁性能进行了仿真分析与验证。首先介绍了软油箱与地面的撞击过程中涉及到的流固耦合理论。然后建立了软油箱的有限元模型,使用MSC.Dytran对软油箱以17.3m/s速度垂直撞击地面的全过程进行了仿真分析,将分析结果与试验结果中的冲击载荷和变形进行对比分析,得出了相关结论。最后研究了材料性能、坠地姿态和外形尺寸对软油箱抗坠毁性能的影响,为抗坠毁软油箱的设计提供理论依据。

| Abstract: | The helicopter flexible fuel cell construction was set as the research object,and its crashworthiness was simulating and validating in this paper.Firstly,Lagrange Euler coupling was introduced theoretically when flexible fuel cell impacting the ground.Secondly,FE model of the flexible fuel cell was founded,and the course of flexible fuel cell vertically impacting the ground at speed of 17.3 m /s was simulating with MSC.Dytran.The simulating results were compare with test results.Lastly,material capability,d... |
