Noise Detection Test System BI-7086N

A typical passive vehicle damper is a compromise between handling properties of a car, passenger comfort and safety as well as NVH (Noise, Vibration, and Harshness). The dominant source of noise in today’s vehicles is from the suspension. This knocking noise (a transient of structural noise) is a result of the subtle vibration of chassis components. It occurs due to the vibrations of the piston rod in the shock absorber, making it a key element of a vehicle suspension system. The piston rod vibrations are caused by the continuous opening and closing motion of the valve, valve impacts, dry friction during stroking inversions and fluid cavitation. The purpose of our system (intended to measure the level of piston rod noise as a quality check of shock absorber in a production line) is ultimately to enhance overall vehicle performance, comfort and to facilitate a seamless transportation
