COMPUTATIONAL PREDICTION OF LOW IMPACT SHOCK PROPAGATION IN A LAB-SCALE SPACE BOLTED FRAME STRUCTURE
2015
Bolted space frames are usually used to allow easy assembly and disassembly, as well as replacing defective components. Although the performance of bolted space frame structures under static loads is well understood, research on the shock propagation through these frames is limited. The focus of this study is to understand shock propagation through space frames, which is a critical factor when assessing the functionality of these frames. In this research, a lab-scale space frame structure, comprising hollow square members that are connected together through bolted joints is constructed. Non-destructive impact testing is carried out on this structure and the resulting acceleration signals at various locations are recorded. The objective of this work is to develop a finite element (FE) modeling approach that can reasonably replicate experimental results.
