Reasons for the application of rubber air springs in vibration equipment
1. Reduce the operating frequency. The greater the stiffness of the rubber air spring material, the greater the stiffness of the air spring, and the higher the first-order resonance frequency, which increases the minimum operating frequency of the system. Therefore, the rubber safety air spring vibration isolation system should reduce the material stiffness and natural frequency, so that the bearing capacity of the air spring vibration isolator can be retained enough, and the minimum operating frequency of the system should be as low as possible.
2. The comprehensive isolation effect is strong. When the vibrating table vibrates laterally, the rigidity of the rubber material of the reed capsule is much larger, the rubber air spring body has a soft structure, and has a comprehensive vibration isolation effect of axial, lateral and rotational steering, and a throttling is set between the air spring and the additional air chamber. valve hole. When air flows through the throttle hole, part of the vibration energy is absorbed due to resistance, which acts as damping and damping.
