NVH damper test system
MTS Systems Corporation

The new Model 853 NVH damper test system by MTS is engineered to address the entire range of damper noise phenomena, including swish, squeak and chuckle.

The advent of quieter electric and hybrid vehicles has created a need for more capable damper NVH solutions. The lighter, thinner materials making up the chassis create an environment where not only air-born ‘swish’ and ‘squeak,’ but also structure-born ‘chuckle’ noises threaten to compromise ride comfort and quality.

To study these phenomena, the innovative Model 853 draws from MTS damper and elastomer testing technologies. The system employs high-bandwidth transducers – typically used in high-frequency elastomer testing – to perform damper NVH measurements with fidelity and accuracy up to 700Hz. It also features an elastomer system’s high-stiffness load frame, along with larger-diameter columns, a thicker crosshead and a more robust base to avoid the resonant modes that can corrupt measurements. Linear electromagnetic actuation technology provides the clean sinusoidal input and low total harmonic distortion (THD) the system requires for effective chuckle testing.

The Model 853 is driven by a versatile FlexTest controller capable of reproducing virtually any type of signal, making it suitable for basic damper characterization and even elastomer testing.
