The suspension for automobiles reduces the vibrations transmitted from the road surface to the vehicle body, which improves vehicle dynamic performance and ride comfort, springs to the shock absorber as the main structure, and oil damper is widely employed in the vibration damping portion. In recent years, in response to the problem of reducing the noise in the car which is called rattle noise, evaluation is required including transient attenuation characteristics of the damper. We construct a damping force characteristic analysis model which considers the transient response of a damper in the car noise prediction system using the 1D model, and the evaluation of transient damping force response near the open operation using this model was obtained.
