Vibration and thermal stresses have long been principal design considerations in achieving high performance requirements for payloads and equipment. Predicting the local dynamic environment involves the use of advanced techniques such as Computational Fluid Dynamics (CFD) to assess the effects of aero– and thermo-dynamic loads. FE and CFD codes ANSYS and Fluent are used together to determine the fluid loading environment upon the structure and the local equipment environment. High frequency vibro-acoustic loads, such as caused by engine noise, are assessed using the AutoSEA 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, fatigue and interior noise.
