Quality Testing for NVH in Vehicle Components – Screen for Resonant Frequencies in NVH-Related Parts

NDT-nvh-application-1

As vehicle engineers have reduced engine and transmission noise levels, brake squeals, groans, other body noise related issues have become an annoyance for the more demanding automotive buyer. In order to increase vehicle sound quality and reduce noise related warranty claims, automotive customers have established brake component specifications for the first set of natural frequencies they expect their suppliers to meet and measure.

NDT-RAM™ effectively handles high volume parts, accurately measures the first set of natural frequencies and stores the data with user customizable fields for tracking part, cavity, weight, etc. Learn more about NDT-RAM.

Screen for Resonant Frequencies in NVH-Related Parts

  • Calipers
  • Discs
  • Knuckles
  • Hubs
  • Anchor Brackets
  • Pistons
  • Bushings

Market-wide warranty repairs for brake NVH claims exceed $100 million annually in the U.S. Objective, economical resonant inspection with NDT-RAM ensures a simple, reliable, affordable means to screen for NVH resonant frequencies, meeting supplier demands and reducing warranty claims.
