1、Air spring has excellent nonlinear hard characteristics, which can effectively limit amplitude, avoid resonance and prevent impact. The nonlinear characteristic curve of the air spring can be ideally designed according to the actual needs, so that it has a low stiffness value near the rated load. 2、Because the medium used by air spring is mainly air, it is easy to implement active control. 3、the stiffness of air spring with load P and k, so under the different load, the vibration isolation system natural frequency is almost the same, vibration isolation effect is almost the same. 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 pressure of the inner chamber. No matter how much load, you can change the air pressure according to the need to adjust the stiffness of the air spring, and you can also increase the volume of the auxiliary air chamber to reduce the stiffness. 5、For an air spring of the same size, when the internal pressure changes, different carrying capacity can be obtained. This makes the same air spring can adapt to the requirements of a variety of loads, so the economy is good. Air spring can bear vertical load, but also can bear a certain lateral load and transfer torque. 6、Increasing the total volume of the air spring can reduce the natural frequency of the vibration isolation system, which is the unique advantage of the air spring. The volume of the air spring body, due to the size of the structural space is limited to a certain extent, it is impossible to be too large. In order to reduce the natural frequency of the vibration isolation system, the auxiliary air chamber can be set up, and the auxiliary air chamber can be arranged in the place far from the air spring. The volume of the auxiliary air chamber increases, that is, the total volume of the air spring increases, and the natural frequency of the air spring vibration isolation system decreases. 7、The air spring can use the height control valve system, so that the air spring under different loads, keep the working height basically unchanged. Similarly, it can also be through the role of height control valve, so that the air spring has different heights under a certain load, so it can adapt to a variety of structural requirements.
