边条翼夹板结构强度设计

The Design of Strake Wing Structural Strength

利用解析与有限元方法分别对3种结构形式的导弹边条翼夹板进行了强度对比分析。分析得出了这3种形式夹板的受力特点以及承载能力的强弱。在此基础上,进一步采用有限元方法对不同形式夹板两两组合运用时的力学性能进行了数值仿真对比,给出了各组夹板的应力分布规律,推荐了较优的组合方案。最后对夹板厚度进行了优化设计。文中研究可为夹板结构设计提供参考依据。

By using analytical and finite element methods, three structural forms of the missile strake wing splint were analysed and contrasted. The stress characteristics and bearing capacity of three kinds of splint was obtained. Basing on this, finite element method was used to simulate and compare the mechanical performance of different types of splint when used in combination, then the stress distribution law of each group of splints was obtained. And a better combination scheme was recommended. At last, optimal design of splint thickness was carried out. This study provided reference for splint structural design.
