  • Modal analysis
  • Frequency response
  • Random vibration
  • Shock response
  • Vibro-acoustic loading
• Develop and maintain finite element models (FEM) for launch vehicle structures and subsystems.
• Support coupled loads and transient dynamic analyses.
• Correlate analytical models with test and flight data.

Data Processing & Interpretation

• Process and analyze vibration, acoustic, and structural response data from:
  • Environmental tests
  • Ground tests
  • Flight instrumentation
• Develop scripts and tools for automated data reduction and visualization.
• Generate PSDs, FRFs, transmissibility, and response spectra.
• Identify trends, anomalies, and correlation gaps.
• Assist in deriving and validating:
  • Random vibration environments
  • Acoustic environments
  • Shock environments
  • Sine vibration profiles
• Support the development of qualification and acceptance test levels.
• Document assumptions, margins, and uncertainties.

Verification & Test Support

• Support dynamic testing activities including:
  • Modal surveys
  • Vibration tests
  • Acoustic tests
  • Shock tests
• Assist with test planning, instrumentation layouts, and data review.
• Participate in test execution and post-test analysis.
