Problems solved by technology
Because it is a single design, it does not have the ability to adjust the additional air chamber of the air spring, resulting in a fixed value or range of its dynamic characteristics. When it is necessary to adjust the gas state in the rubber capsule, it cannot be effectively adjusted.
In the process of project use, it can only be configured or designed for specific projects, once the design and construction are completed, it cannot be changed
[0004] (2) poor stability
When a single main air chamber or only one additional air chamber is used, due to the uncontrollable gas flow rate during the inflation or exhaust process, when the gas flow rate is high, the air spring will deform unstable and sometimes vibrate due to the single gas diffusion path. Vibration, long stabilization time, not conducive to vibration control
[0005] (3) Poor construction technology for damping adjustment
Due to the single function of this solution, and once the additional air chamber is determined, it can only be adjusted through the orifice, so if a simple adjustment is made, the air spring needs to be disassembled for each adjustment, and then the orifice ring is replaced, and then Then install the air spring and test it. If the requirements are not met, the air spring will be disassembled and replaced again. Repeat this, so the damping adjustment construction process is poor.
[0006] (4) The damping adjustable range is narrow and the controllable precision is low
Once the inherent properties of the air spring are designed and processed, they cannot be changed, resulting in a single way for the air spring to adjust the air state, and sometimes it cannot be adjusted.
Moreover, when the damping of the air spring needs to change the adjustment range and improve its controllable precision, this traditional solution cannot be realized, resulting in a narrow damping adjustable range and low controllable precision
In severe cases, it will lead to failure of air spring design and processing

The invention provides a control method for an air spring structure of a variable additional air chamber. A main air chamber with an ordinary film type air spring structure, a first-level additional air chamber, a second-level additional air chamber and a third-level additional air chamber are mainly included. The main air chamber and the interiors of all levels of additional air chambers are sequentially connected through throttling holes. The throttling holes of all levels of additional air chambers are different in hole diameter. Air supply branches and control valves of all levels of additional air chambers are connected to a main air supply path and a main air supply valve in parallel so that the control valves of all levels of additional air chambers can be adjusted, and one air spring device can become a device with different numbers of additional air chambers. The inflation control valves of the additional air chambers can be adjusted according to the requirement of the actual project; on one hand, the system balance process is stable through changing of a gas circulation pass in a multi-level manner; and on the other hand, through controlling over the flow speed of gas flow, the controllable range of gas damping is widened, and the controllable precision of gas damping is improved.
Description
technical field [0001] The invention relates to a control method of a variable additional air chamber air spring structure. Background technique [0002] At present, the high-precision air springs for the micro-vibration control system in the precision manufacturing industry are all single design schemes, such as a single main air chamber structure or a single additional air chamber structure, which only corresponds to one implementation. For the air spring, since it mainly relies on the gas state characteristics in the rubber capsule for vibration reduction, this single solution cannot effectively change the role of the additional air chamber to control the gas state. In many cases, when the use function changes or the external vibration load Changes in characteristics will cause the air spring to fail to meet the design goals and cause instability. This scheme has the following defects: [0003] (1) The use function is limited. Because it is a single design, it does not...
