Brüel & Kjær Sound & Vibration Measurement Military Vehicle Noise and Vibration Measurement Solutions

Brüel & Kjær is a world-leading provider of noise and vibration test and measurement solutions for operational, production and R&D applications. Solutions cover acoustic, rotating, structural, military vehicle, gunshot noise and environmental testing for the civilian, military and space industries.

Brüel & Kjær specialises in systems that ensure structural reliability, performance and optimal design, and manage the acoustics of military equipment and vehicles for air, space, ground and underwater use.

Military vehicle noise testing

Covering the entire measurement chain for comprehensive noise and vibration testing:

  • Transducers
  • Acquisition hardware
  • Vibration shaker systems
  • Analysis software
  • Final documentation and reporting

Environmental noise impact testing and monitoring

With increased focus on environmental noise impact testing and monitoring, responsible organisations are looking for ways of reducing their environmental noise impact on armed forces personnel and local communities.

Brüel & Kjær supplies systems for occupational health, helmet / cabin / cockpit noise assessment, acoustic and human vibration monitoring, urban noise monitoring and noise-mapping of vehicles:

  • Occupational health
  • Helmet / cabin / cockpit noise assessment
  • Human acoustic and vibration monitoring
  • Urban, airport, industrial and construction noise monitoring
  • Vehicle noise mapping

Acoustic stealth detection for less detectable noise footprints

Acoustic stealth and acoustic discretion play a vital role in submarine operations. Brüel & Kjær supplies systems for acoustic ranging of submarines and surface ships, for noise source investigation during design and build, and for self-monitoring during operations.

Above the water and up in the skies, UAVs are playing an increasingly important defensive role, and have needs, just as with submarines, to be less detectable. Noise footprint assessment and noise characterisation are important. Brüel & Kjær designs and builds arrays for noise source identification:

  • Noise source investigation during design and build
  • Self-monitoring during operation
  • Noise footprint analysis
  • Noise source identification
  • 3D noise mapping
  • Underwater acoustic ranging

Durability testing systems

For any aircraft, helicopter, space vehicle or ballistic device reliability is the number one priority.

By using our noise / vibration detection and shock testing systems, transducers and high-speed data acquisition systems, a product’s reliability and integrity can be proven:

  • Accelerated lifetime vibration testing
  • Fatigue testing
  • Climatic simulation
  • Package testing

Engine and gearbox monitoring

Stringent engine and gearbox monitoring through vibration analysis of rotating machinery provides valuable information on engine health, reliability and performance.

Brüel & Kjær HUMS (Health Usage Monitoring Systems) transducers are permanently mounted on gearboxes of civilian and military helicopters.

Our vibration measurement and analysis solutions are found in both test-cell applications and on-ground maintenance systems:

  • Test-cell applications and on-ground checks
  • Balancing
  • Vibration diagnostics using real-time analysis
  • HUMS transducers

Structural dynamics testing

Structural dynamics and the testing of structures is essential to understand and optimise the inherent dynamic properties of structures to ensure reliable and safe operation.

Brüel & Kjær’s structural test suite offers complete solutions for controlled excitation testing, real-life operational testing and test-FEA integration from the smallest components to the largest assembled structures:

  • Controlled excitation testing
  • Classical and operational modal analysis
  • Operational monitoring, testing and troubleshooting
  • Virtual model validation
  • Operational deflection shapes

Brüel & Kjær has over six decades’ experience of providing innovative solutions for noise and vibration testing:

  • More than 90 sales offices in 55 countries
  • 12 accredited calibration centres
  • R&D engineers in Denmark, UK, USA and India

Brüel & Kjær has the largest global service organisation within sound and vibration.
