Vibration, acoustic and thermal stresses have long been principal design considerations in achieving high performance requirements for ruggedising equipment to survive harsh environments. Predicting the local dynamic environment involves the use of advanced techniques such as Computational Fluid Dynamics (CFD) to understand and assess the effects of dynamic loads. Advanced analyses are used to determine the loading environment upon local equipment and supporting structure. High frequency vibro-acoustic loads, such as caused by engine noise, are assessed using the VA One Statistical Energy Analysis code.

Vipac has extensive design, analysis, and test experience with noise and vibration control in military vehicles, aircraft, and underwater-radiated noise from marine platforms. Typical assessments include thermo-dynamics, acoustic emissions, structural dynamics (including fluid structure interaction), fatigue and interior noise.
