The Challenge

• Design advanced composite satellite structures that are lightweight but that can also withstand the harsh acoustic environments encountered during launch.
• Assess the transmission of acoustically induced vibration into attached equipment to determine equipment qualification levels.
• Model the response of large complex systems subjected to random vibro-acoustic loading across a broad frequency range.

The Benefits

• Dynamic stress prediction guides the design of critical components subjected to random vibroacoustic loads.
• Unique combination of low, mid and high frequency analysis methods in one tool results in faster model creation and simplified model management.
• Customization through scripting to integrate with existing in-house methods for strength calculation. 
• A structural engineer with one year of experience can be productive with the software after only a minimal amount of in-house training.

“VA One meets our needs for the vibro-acoustic analysis of spacecraft across the entire frequency range. With a single tool we can account for all the vibro-acoustic loads on our satellites.”

Mr. José Luis Riobóo, Responsible for Engineering Organization at EADS CASA ESPACIO.
