Boeing adopts AutoSEA2 shock analysis to assess risks during orbital assembly of the International Space Station (ISS)

Vibro-Acoustics
Aerospace & Defense
The AutoSEA2 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 AutoSEA2 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

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 AutoSEA2 Shock Module.
