Damper NVH Test Systems

Accurately replicate a broad spectrum of damper and shock absorber noise and vibration phenomena, including elusive, structure-borne “chuckle” noises that can prove especially degrading to the ride comfort and quality of electric and autonomous vehicles. The innovative Model 853 Damper NVH System is purpose-engineered for conducting high-fidelity damper NVH measurements at up to 700Hz - essential for meaningful chuckle analysis. The versatile Model 853 is also well-suited for elastomer testing applications.

Applications

  • NVH
  • Characterization
  • Dynamic Characterization

Test Specimens

  • Dampers
  • Struts
  • Elastomeric Components
