A recent trend within the automotive industry has been an emphasis on the reduction of noise future vehicle applications. This trend created a need for the development of methods to predict the noise within the vehicle environment. In particular, the development of models for the reduction of noise must be based the result that account for the dynamic property between components. The noise vehicle in driving is mostly transferred through the suspension system or created from the damper. So, the information of parameter for the damper noise is very important to characterize the vehicle noise. After the loading conditions is performed with real vehicle installing condition, this paper describes a finite element model of a damper model with the clearance between and rod guide and rattle the suspension system. The results of a study of the damper noise subjected to dynamic loading condition and rattle the suspension system. The results of a study of the damper noise subjected to dynamic loading condition are presented. Additionally, the effects of the clearance in the damper are considered and the results are displayed.

Brake judder in automotive vehicle is defined as low frequency vibration around 20Hz caused by disc thickness<br/> variation of disc brake. This paper is focused on developing simulation model to analyze the transfer pass of brake<br/> judder phenomenon of chassis system, which is composed of suspension, steering, brake systems. A dynamic model<br/> of half car system was constructed with ADAMS software and validated by experimental data in chassis dynamometer<br/> test.
