Abstract:
Clamp band joints are commonly employed as mechanical fasteners of the launching system in the aerospace industry. Appropriate modeling of the joint stiffness is essential to predicting the dynamic behavior of the launching system accurately and efficiently. In this paper, an analytical model for the bending stiffness of the clamp band joint is developed and then validated by finite element analyses. The bending behavior of the clamp band joint is studied using the proposed analytical model. Parametric studies are also performed to investigate the effects of the preload and the structural parameters on the bending stiffness of the clamp band joint.
