Abstract: The development of automobile technology has made ride comfort and handling the core of design. The limitation of traditional passive suspension systems is that they cannot be adjusted to adapt to changing driving conditions. The application of air spring suspension technology provides a solution by adjusting the air pressure to change the suspension stiffness and height. The system can maintain a constant bias frequency under different loads, enhance smoothness and stability, automatically adjust to different road conditions, reduce vibration, and improve comfort. This study uses a swept frequency excitation test to measure the acceleration response at different positions of the vehicle and analyze the transfer characteristics. The results show that the air spring suspension can significantly reduce the body acceleration and tire dynamic deformation under various working conditions, confirming its advantages in improving ride comfort and handling stability. These findings provide experimental support for the design of air spring suspension and promote its widespread application in modern automobiles.
