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.
