Noise & Vibration

Topics: Operational Modal Parameter Estimation, Load and Source Identification, 
Structural Health Monitoring, Advanced measurement techniques
 
Goals
 
  • Identifying time-varying wind loads and acoustic sources on structures from in situ vibration responses and pressure data using inverse methods
  • Identifying the dynamic behavior from structures during their operating conditions, using responses only by using advanced operational modal analysis techniques for rotating machines
