Selection And Calculation Of Gas Springs

The air spring can maintain its natural frequency unchanged under any load, can bear radial and axial loads at the same time, and can also transmit a certain torque. Different load-bearing capacities can be obtained by adjusting the internal pressure.

Gas spring working principle:

Inert gas or oil-gas mixture is filled into a closed pressure cylinder to make the pressure in the cavity several or dozens of times higher than the atmospheric pressure. This is achieved by using the pressure difference generated by the cross-sectional area of ​​the piston rod being smaller than the cross-sectional area of ​​the piston. Movement of the piston rod. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler (inert gas or oil-gas mixture), in-cylinder control components and external control components (referring to controllable gas springs) and joints, etc. Due to fundamental differences in principles, gas springs have significant advantages over ordinary springs: the speed is relatively slow, the dynamic force does not change much (generally within 1:1.2), and it is easy to control; the disadvantage is that the relative volume is not as small as the coil spring and the cost High and relatively short life.

According to its characteristics and application fields, gas springs are also called support rods, angle adjusters, air pressure rods, dampers, etc. Currently, this product is widely used in automobiles, aviation, medical equipment, furniture, machinery manufacturing and other fields. Its characteristic line of the relationship between deformation and load is a curve, which can be designed according to needs. There are many structural forms of air springs, including bladder type and membrane type. They are often used in vehicle suspensions and anti-vibration systems of mechanical equipment. Gas spring is an industrial accessory that can perform functions such as support, buffering, braking, height adjustment and angle adjustment. It consists of the following parts: pressure cylinder, piston rod, piston, sealing guide sleeve, filler (inert gas or oil-gas mixture), in-cylinder control components and external control components (referring to controllable gas springs) and joints, etc. The principle is to fill a closed pressure cylinder with inert gas or oil-gas mixture, and the pressure in the cavity is several or dozens of times the atmospheric pressure. When the gas spring acts, the pressure difference on both sides of the piston is used to realize the movement of the piston rod. Due to fundamental differences in principle, gas springs have significant advantages over ordinary springs: relatively slow speed, small change in dynamic force (generally within 1:1.2), and easy control.

The disadvantages of gas springs are that they are not as small as coil springs, have high costs, and have a relatively short lifespan. Unlike mechanical springs, gas springs have a nearly linear elastic curve. The elastic coefficient X of the standard gas spring is between 1.2 and 1.4, and other parameters can be flexibly defined according to requirements and working conditions.

Types of gas springs
A spring made by exploiting the compressibility of air in a closed container. According to the structure and function of gas springs, gas springs include free gas springs, self-locking gas springs, traction gas springs, random stop gas springs, swivel chair gas springs, air pressure rods, dampers, etc.

Kitchen cupboard gas struts are a convenient and space-saving solution for cabinet doors. These struts assist in smoothly opening and holding cabinet doors in the open position, allowing easy access to kitchen essentials while keeping the space neat and organized. 

For door applications, gas shocks for doors are an extremely convenient device that make opening and closing the door effortless. These levers reduce user effort while keeping the door securely open or closed when needed. This allows gas struts to provide more convenience and reliability in door use. 

 Tailgate gas struts also play a key role in the car's tailgate support. They allow the tailgate to be easily lifted, giving the user convenient access to the storage space at the rear of the vehicle. The tailgate support struts improves the convenience of the car's tailgate.
