目的 针对复合材料发射箱定向器的结构进行优化设计。方法 通过材料力学理论，计算并结合有限元仿真分析，对定向器进行结构优化设计。结果 定向器的最大变形满足指标要求，最大应力低于材料屈服强度。结论 该设计方法便捷可靠，为今后类似产品设计提供了思路参考。

The work aims to optimize the structural design of composite guide of launch canister. Based on the theory of mechanics of materials, the calculation and simulation analysis combined with the finite element were carried out to optimize the structural design of the guide. The maximum deformation of the guide met the index requirements and the maximum stress was lower than the material's yield strength. The proposed design method is convenient and reliable, and provides a reference for future similar product design.
