Abstract

Shock transfer performance of joints has substantial influence on the dynamics of assembled structures as they induce a large amount of damping into the structure. Study of shock transmission through the various jointed (both mechanical and adhesive) components of the combat vehicle is of particular interest to the army. The principal objective of this work is to develop solutions that enable ARL to generate improved physics-based shock models for lightweight combat vehicles focusing mainly on shock transmission across structural joints. Shock transmission through two identical simple hat sections joined together with different joint configurations like adhesive bonding and bolted joints has been studied to understand the shock response of a full scale light combat vehicle. It was observed that the finite element results from the adhesively jointed double hat sections with spacers (both, continuous and intermittent) show better congruity with the experimental results when compared to the double hat sections with bolts.
