New NVH damper test system for structure-borne noise assessment
Demands for improved suspension NVH are driven by quiet EV and comfort-focused autonomous vehicle trends. Noise is emitted from the damper through airborne and structure-borne transfer paths. MTS has developed a unique damper test system to evaluate structure-borne noise and vibration. Traditional damper systems evaluate damper characteristics in the lower suspension motion frequencies, typically less than 50 Hz. For evaluating structure-borne noise, precise excitation and measurement in audible frequencies up to 800Hz is necessary. This new NVH damper system achieves high frequencies using an electric actuator, high resonant frequency frame and high bandwidth transducers.
