Damper is an important component that can control system vibration and is widely used in machinery, aerospace, automotive and other fields. There are many types of dampers . This article will introduce several common dampers and share some practical experience in using dampers.
1. oil damper
oil damper is an important damper used in the aerospace field, mainly used to alleviate the vibration of the wing. It is by injecting liquid into the structure of the wing, so that the liquid interacts with the structure to produce friction, thereby slowing down the vibration.
In actual use, oil dampers are often installed in the cavity between the wing and the fuselage of the aircraft. When the oil is introduced into the cavity, a liquid film is formed between the wing and the fuselage, which allows vibration to be mitigated. However, it should be noted that the oil will be continuously lost and need to be replaced regularly, otherwise it will affect the effect of the damper.
2. Hydraulic Damper
Hydraulic damper is a damper that controls system vibration through hydraulic action. It is mainly used in automobiles, ships and other fields, which can effectively reduce the vibration and noise of vehicles during driving.
Hydraulic dampers are usually composed of hydraulic cylinders, pistons, valves and other components. When the system vibrates, the liquid in the hydraulic cylinder will be under pressure, which will cause the piston to move, and then drive the valve to open or close, realizing the adjustment of the damper. Hydraulic dampers have the advantages of fast response, high control accuracy and good stability, so they are widely used in automobiles, ships and other fields.
3. air pressure damper
air pressure damper is a damper that controls system vibration through air pressure. It is mainly used in the aerospace field and can effectively reduce the vibration and noise of the aircraft during flight.
Air dampers are usually composed of pneumatic cylinders, pistons, valves and other components. When the system vibrates, the gas in the pneumatic cylinder will be under pressure, which will cause the piston to move, which in turn drives the valve to open or close, realizing the adjustment effect of damper . Pneumatic dampers have the advantages of fast response, high control accuracy and good stability, so they are widely used in the aerospace field.
4. air damper
air damper is a damper that controls system vibration through air action. It is mainly used in buildings, bridges and other fields, which can effectively reduce the damage of buildings and bridges in natural disasters such as earthquakes.
Air dampers are usually composed of air chambers, pistons, valves and other components. When the system vibrates, the air in the air chamber will be under pressure, which will cause the piston to move, which in turn drives the valve to open or close, realizing the adjustment of the damper. Air dampers have the advantages of fast response, high control accuracy and good stability, so they are widely used in buildings, bridges and other fields.
In short, the damper is an important system control component, which is widely used in machinery, aerospace, automotive and other fields. In actual use, it is necessary to select the appropriate damper according to the specific needs of the system, and pay attention to regular maintenance and replacement to ensure its effect and reliability.
