  1. Suction manifold Discharge manifold Discharge valve Suction valve Cylinder wall Piston Project: Multi-Cylinder CompressorModeling and Simulation Sponsors: Sanden Corporation Goals: Model and simulate compressor thermodynamics, valve dynamics, and manifold acoustics to identify design changes leading to reduced operational noise. Cylinder control volume Valve and manifold design changes

  2. Near field Sound source Non-contact sensor Panel Project: Material Damage Modeling and Detection Using Acoustic Transmission Sponsors: Air Force Research Laboratory Materials Directorate Goals: Use a non-contact means of sensing to identify material damage in metallic panels. Material Damage Modeling Acoustic Transmission Testing Test setup Near-field Damaged panel

  3. Project: Effects of Fuselage Window on Structure and Airborne N&V Sponsors: U.S. Coast Guard Goals: Identify possible changes in the vibration and noise environment inside of a C-130J fuselage due to insertion of window to enable search and rescue missions. Changes observed in vibration Fuselage panels tested  vibration below 200 Hz

  4. Project: Model Identification and Vibration Control for Exhaust System Sponsors: ArvinMeritor Goals: Develop experimental sensitivity techniques for deriving dynamic model of an exhaust system, and identify optimal design changes to reduce structure-borne noise/vibration. Exhaust system tested Design changes implemented

  5. Project: Damage Identification in Structural Systems Sponsors: Air Force Research Lab Goals: Identify damage in a variety of specimens using propagating waves and active piezoelectric arrays. Structural SpecimensDamage Identification Damage Location Increasing Complexity
