With each new model year, automotive interiors become quieter, and noises that once were masked now become more prominent. As the use of plastics and elastomers becomes more prevalent there becomes an increased risk of frictionally incompatible materials contacting each other, resulting in squeaks, ticks, itch… i.e. objectionable noise. In the specific case of automotive seals (static and dynamic weatherstrips), we must be able to provide up-stream performance information to Forward Model Design Engineers, so they can make educated selections of acoustically and frictionally compatible materials. Ford's NVH S&R Department and MB Dynamics have developed a tester that can measure friction, and any accompanying audible sound, as a function of sliding velocity (single event, sine, random, or road load), normal load, surface roughness, and environmental factors.
