Acoustics + Vibrations

APC AkkustikAPC has many years of experience in the areas of acoustic and vibration investigations. Our spectrum of services includes in particular the interaction of engine and turbocharger systems with investigations and analyses on individual components, applications in vehicles and the analysis of transfer paths.

The following topics form the main focus of our services and consultations:

Acoustic vibrations

  • Frequency analyses, operational vibration analyses, determination of modal parameters
  • Natural frequency measurements, Campbell diagrams
  • Vibration analyses in connection with engines and turbo-machines
  • Measurement and assessment of imbalance on turbo-machines
  • Measurement of air and structure-borne sound
  • Measurement of acoustic pressure, acoustic levels and acoustic power levels

Rotor dynamics

  • Rotor vibration simulation + measurements on rotors
  • Determination of critical speeds, rotor stability
  • Vehicle acoustics
  • Transfer path
  • Source locating and diagnosis
  • Run-up/coast down measurements
  • Modal analysis
