Boeing adopts VA One shock analysis to assess risks during orbital assembly of the International Space Station (ISS)

Vibro-Acoustics
Aerospace & Defense
The VA One Shock Analysis tool enabled Boeing and NASA to assess potential damage to Space Station electronic boxes that might occur from inadvertent impacts during on-orbit assembly. The VA One Shock Module ensured that the current assembly operations would not affect critical Space Station hardware, and eliminated the need to implement expensive operational and hardware changes.

Challenge

To assess the potential vibration shock damage to the SSU due to an astro- naut or robotic arm operation impact- ing a critical electronics box. To perform a dual analysis approach using both FEA and SEA methods to span the entire relevant frequency range.

Benefits

A quick and effective modeling tool for high-frequency assessment of shock vibration response. Confidence in the results based on the methodology and proven methods used by the VA One Shock Module.
