Shock Response and Acoustic Radiation Analysis

Accurate numerical modeling of the shock response of marine structures is of considerable importance in their design since the cost associated with physical testing is often prohibitive. Along with the shock response calibra-tion, designers often have to grapple with opposing fac-tors while trying to optimize performance during operating conditions. Abaqus allows for the analysis of both the structural integrity and acoustic radiation in such cases.

In this technology brief two related but distinct analyses are examined. First, the shock response of an example structure due to a shock event is considered. Second, the steady-state acoustic field established due to machinery-induced vibrations within and around the structure is esti-mated.
