Welcome to the Structural Dynamics Group

Daniel Kaufman, Group Leader

The Structural Dynamics Group ...

Conducts
• Structural analysis utilizing NASTRAN and/or other programs in support of the design, analysis and qualification testing of flight structures. This includes finite-element math modeling and coupled spacecraft / launch vehicle loads analysis. The group provides GSFC-managed Projects with lead and support structural analysts.
Performs
• Vibroacoustic modeling and analysis (frequency response analysis)
  - Random Vibration
  - Sine Vibration
  - Acoustic
• Modal analysis (normal modes)
• Transient analysis
• Coupled loads analysis and data post processing
• Shock analysis
• Structural test simulation
• Math model correlation
• Microphonics and on-orbit disturbance analysis
• Mass properties, static and dynamic balance
• Dynamic data processing
Prepares
• Structural environmental requirements documents
• Test Plans and reports for developmental and qualification tests
Supports
• Independent technical assessments
• Consultation to agency and projects
• Peer reviews
• Flight project reviews and test/launch anomaly investigations
