导弹支撑方案的载荷优化设计方法

摘要

A missile may bear severe mechanical environment during ground parking, lifting, erecting and transportation. Therefore, it is important to choose a proper transportation support scheme for reducing the load during ground operations, improving the missile load environment, and enhancing the reliability and safety of missile launching. An optimization design method for auxiliary support stiffness and support position is given based on finite element method and simplex method. Its result shows that the optimization method can significantly improve the load environment.%导弹在地面停放、起吊、起竖、运输等工况下往往承受比较严酷的力学环境，如何选取合适的运输支撑方案对于降低导弹地面操作载荷、改善导弹载荷环境条件、提高导弹发射的可靠性和安全性具有重要的作用。用有限元方法和单纯形最优化方法给出一种辅助支撑刚度和支撑位置的优化设计方法，结果表明优化设计方法对导弹载荷环境有显著改善。
