Design for undex survivability of an integrated modular mast
conference paper
Thales Naval Netherlands is currently developing a so-called Integrated Modular Mast (IMM), thereby supported by the Royal Netherlands Navy and TNO. There is a need for knowing the response of this IMM to underwater shock in such a way, that this can be used in the design of shock resistant sensor arrangements and equipment mountings. In this study, underwater explosion (UNDEX) response analyses were performed for an IMM mounted on different frigate hulls. These analyses were done using the so-called Simplified Interaction Tool, an add-on to LS-DYNA. This provided insight in the shock environment inside the mast. The calculated shock motions were fitted with standard shock pulses for use in equipment specifications. Subsequently, a failure analysis was done for a composite sandwich radome, an IMM component with various adhesive bonded joints. This analysis was performed with the so-called Failure Prediction Tool. The failure behavior of the radome materials was obtained from material tests.
