Locking and unlocking systems for airbags


1. Airbag locking system If the airbag is not connected to the air source to control the height or has no air valve device, it is called a locking system. The system uses a fixed amount of gas as the elastic medium. A certain amount of gas is enclosed in the system, and the amount of gas remains unchanged under pressure and rebound.


2. Unlocking system of airbags
Unlocked systems for airbags are the most commonly used today. The air bag is connected to the air source through a height control or other air valve device, which is called an unlocked system. Whether at rest or under pressure, the bladder maintains relatively the same volume at the design operating height. Under the fixed condition of the height valve, the load force and elastic coefficient change with the change of the pressure of the fixed gas. With this system, the additional pressurized gas maintains the height of the air bag even as the air bag load changes. In this way, in the case of changes in load, since the system can keep the volume of the airbag unchanged, the natural vibration is more stable than the locking system. In short, the natural vibration frequency of the system will not change when the load changes.

 

 

Advantages of airbags
1. The elastic coefficient of spring expansion can be controlled;
2. Adjustable load carrying capacity;
3. Easy to achieve height control;
4. Reduce friction;
5. The load changes, but the natural frequency is basically unchanged.
