The poor vibration absorption performance and large amplitude of seat during driving are common in vehicle development and market compliant. This paper establishes forced vibration and free vibration models of seat, and proposes a prediction method of seat vibration absorption performance. Then it analyses a ventilation seat by FTA method, and identifies factors that affect vibration absorption performance, such as seat weight, foam hardness, foam structure, ventilation bag hardness, suspension mat stiffness, whether suspension mat can deform freely or not, foam damping and so on. Finally, this paper proposes the countermeasures, and confirms that the above design method is effective by bench test and vehicle evaluation. This paper will provide reference for the design of seat vibration absorption performance.
