利用有限元方法对火箭炮定向器的模态进行了静力学仿真分析。分别分析了自由模态下和约束模态下的定向器固有频率。自由模态下的仿真结果为定向器的初期研制和改进提供了理论参考，约束模态下的仿真结果为定向器的实际工作状态提供了参考，防止定向器在工作状态时发生共振。

The modal analysis of the director of a rocket launcher was carried out by finite element method ,the natural frequencies of the director were calculated in the free mode and constraint condition respectively .The results can provide the theoretical reference to the development and improvement of the director ,and prevent it from resonance in working state .
