导引头天线在高过载环境下的动态响应分析

目的 研究末制导炮制导引头天线在高过载环境下的结构动态响应。方法 针对末制导弹采用火炮发射的内弹道段短时高过载的载荷环境特点，通过理论分析与实验研究相结合，对结构的模态，阻尼特性进行了分析，并对其在高过载环境下的动态响应进行了分析。结果与结论 分析表明导引头天线结构的动态应力和位移满足强度要求和使用条件，为结构设计提供了依据，同时，研究方法也适用于未制导炮制其它结构的分析。

Dynamic Response Analysis of Seeker Antenna under High Over Load

Aim To discuss the dynamic response of seeker antenna of guided projectile under high over load. Methods Theoretic analysis and experimental research were conducted to analyze the mode and damping property of seeker antenna of guided projectile. And the dynamic response of the antenna under high over load was studied with FEM. Results and Couclusion The dynamic stress and displace ment of antenna can meet the requirements of design. And the methods can be used to analyze the other internal components of guided projectile.
