Abstract
A new single-attachment air spring system with a parallel one-way tube is designed as a vibration isolation device for vehicles. The dynamics model of the new two-throttle tube air spring is established first, and the accuracy of the two-tube model is verified experimentally. Finally, the experimental results of the two-throttle tube air spring and the single-tube air spring are compared to analyze the effects of the tube diameter, tube length and additional air chamber volume on the dynamic stiffness of the two-throttle tube air spring. The results show that the combination of throttle tubes of different diameters has a great influence on the stiffness and damping characteristics of the air spring. Compared to single-throttle tube air springs, an air spring with a single additional air chamber in parallel with a single-throttle tube can provide different sizes of damping during extension and compression of the air spring, which improves the cushioning and damping capability of the air spring. And the two-throttle tube air spring can eliminate the inertial influence of the air flow in the throttle tube, significantly reduce the dynamic stiffness of the air spring, and at the same time, the change of the dynamic stiffness of the air spring within a certain frequency range is reduced, so as to avoid the adverse effect of the excessive dynamic stiffness change rate on the performance of the air spring.
