摘要
阐述了多联装发射装置模态分析的重要意义,然后基于软件,用有限元法求解了某型多联装发射装置的一阶固有频率和振型,并进行多次仿真试验,探讨一般性规律,通过与相关文献进行比较,验证了研究方法的有效性.
The importance of modal analysis of the multiple launching system is expatiated. Then based on finite element software, the solving of the first natured frequency of one multiple launching system is approached and simulated. In order to verify the availability of researching methods, the universal rules were looked for and compared to some other literatures.
