The work aims to design a kind of vibration-absorbent airbag with two degrees of freedom, simulate the transport process of the complete vehicle and calculate the vibration absorption performance of the structure for simulation and verification, so as to lay a foundation for the follow-up study on the vibration absorption of shipping packaging for the complete vehicle. According to the D'Alembert's principle, the theoretical model of packaged fragile parts in the transport process was simplified and the kinematic equations were established. The time domain model of filtered white noise was simulated and solved by Simulink and other software. Three vibration analysis diagrams associated with traffic safety was obtained by vibration model analysis. Finally, the evaluation mechanism suitable for the vibration model was established. The amplitude and the angle change range of vibration-absorbent airbag is 0.02 m and 0.004~0.009 rad when the normal speed of 40~50 km/h. In the transport process of the relevant fragile parts, the vibration-absorbent airbag system based on the two degrees of freedom is of good reliability.
