What are the advantages of air springs?

1) The air spring has excellent nonlinear hard characteristics, which can effectively limit the amplitude, avoid resonance, and prevent impact. The nonlinear characteristic curve of the air spring can be ideally designed according to actual needs, so that it behaves with a lower stiffness value near the rated load.
2) Since the medium used by the air spring is mainly air, it is easy to implement active control.
3) The stiffness k of the air spring changes with the load P, so under different loads, the natural frequency of the vibration isolation system is almost unchanged, and the vibration isolation effect is almost unchanged.
4) The stiffness of the air spring is adjustable, and the stiffness of the system can be changed by changing the volume of the air chamber or the inner cavity pressure. No matter how much the load is, the air pressure can be changed as needed to adjust the air spring stiffness, or the internal volume of the auxiliary air chamber can be increased to reduce the stiffness.
5) For the same size air spring, when the internal pressure changes, different bearing capacities can be obtained. This allows the same air spring to adapt to a variety of load requirements, so it is economical. While bearing vertical load, air spring can also bear certain lateral load and transmit torque.
6) Increasing the total volume of the air spring can reduce the natural frequency of the vibration isolation system, which is a unique advantage of the air spring. The volume of the air spring body cannot be too large because the size of the structure space is limited to a certain extent. In order to reduce the natural frequency of the vibration isolation system, an auxiliary air chamber can be set up, and the auxiliary air chamber can be arranged away from the air spring. The volume of the auxiliary air chamber is increased, that is, the total volume of the air spring is increased, and the natural frequency of the air spring vibration isolation system is reduced.
7) The air spring can use the height control valve system to keep the working height of the air spring basically unchanged under different loads. Similarly, through the action of the height control valve, the air spring can have different heights under a certain load, so it can adapt to various structural requirements.
8) The air spring can absorb high frequency vibration and has excellent sound insulation performance.
Air springs are mainly composed of rubber bladders and air. During the vibration process, the rubber bladder has little internal friction due to expansion and warping, so it is difficult to transmit high-frequency vibration. Air and rubber do not transmit sound easily, so they have good sound insulation properties. The steel spring is easy to transmit high-frequency vibration, but also easy to transmit sound.
9) If an orifice is set between the main air chamber and the auxiliary air chamber of the air spring, when the air spring vibrates and deforms, there will be a pressure difference between the main and auxiliary air chambers, and the air flows through the orifice and absorbs a part of the energy due to resistance. , so it has a damping effect. A suitable orifice diameter can improve the damping characteristics of the vibration isolation system and effectively suppress the resonance amplitude.
10) The air spring is light in weight. In addition to the rubber bladder and almost weightless air, its body is the upper and lower covers, so it is much lighter than the steel spring.
