| 摘 要： | 基于模型导弹的结构参数,通过有限元方法计算了6种建模方法对应模型的模态,研究了导弹内部分支结构动力学建模的6种方法对全弹模态计算结果的影响.研究发现:考虑分支结构对全弹刚度的影响时,模态计算结果与试验结果较接近;另外细化考虑导弹对分支结构的约束效果时,模态计算结果最接近试验结果.

| Abstract: | Based on the real parameter of the rocket, the modes for the six models were simulated by FEM method to analyze the influence of the six models on the rocket's modes.It is found that the model are more closed to the experimental results when the branches are modeled, and the model are most close, considering the constraining relationship between the branches and the rocket. |
