What is the principle of air spring application in different industries?

When it comes to the application of air springs, I believe everyone is most familiar with the application in the industrial industry! But in fact, in addition to the industrial industry, there are many other industries that have also applied air springs. So what is the principle of air spring application in other industries? We know that air spring has nonlinear characteristics, so its stiffness changes with the change of load, so its natural frequency remains almost constant under any load, which also makes the spring device have almost constant characteristics; The air spring has good high-frequency vibration absorption and sound insulation performance; It bears axial load and radial load at the same time, and different bearing capacity can be obtained by adjusting internal pressure. It also shows that it can meet the needs of various loads. Let's take a look at the application of air springs in different industries! 1. Machinery industry: Air springs are widely used for equipment vibration isolation in industrial machinery industry, and are used for precision mechanical equipment and precision test equipment such as presses, air compressors, centrifuges, vibrating conveyors, control hammers, casting machinery and textile machinery, optical and laser instruments, integrated circuits and ultra-precision machine tools. With the improvement of people's living standards, people have higher and higher requirements for reducing vibration and noise interference, so there will be more and more air spring vibration isolation technologies in the future, so its application prospect is very broad. In mechanical vibration isolation technology, air springs generally adopt constrained membrane structure and free membrane structure. Air springs are used in all kinds of mechanical equipment, mainly for buffering and absorbing vibration, controlling movement or pressurizing. Compared with the same type of equipment, the air spring has the advantages of simple structure, reliable operation, no complicated parameter calculation and structural design, no sealing leakage problem, convenient use and maintenance and long service life. 2. Paper-making, textile and other industries: In the paper-making and textile industries, paper or cloth needs to bypass many conveying rollers at high speed in the winding process, so constant tension is needed in the conveying process, which can effectively avoid loosening, twisting or cracking of paper or cloth. In this case, the combined structure of hollow winding roller and air spring can effectively provide constant tension. But also has strong impact load bearing capacity, thus protecting the conveying device and conveying parts from being damaged. This also shows that the air spring is very suitable for high pressure and small stroke. Using air spring in the bonding process can provide uniform pressure and ensure the bonding quality. Practice shows that air spring has better buffering effect than steel compression spring, which can effectively improve equipment efficiency and prolong equipment service life. Air spring is the gospel of our mankind, and keeping the car in the best comfort state is the gospel of our mankind, and keeping the car in the best comfort state. With the progress of science and technology, people's quality of life has improved, at the same time, the quality of roads and pavements has also been continuously improved, and the speed of vehicles has become faster and faster. Therefore, the requirements for vehicle comfort will naturally increase, and springs will gradually leave the field of passenger cars and small cars; Another kind of metal spring began to slowly climb to the dominant position-coil spring. Everyone is familiar with the coil spring: from small household toys to large furniture, it is everywhere. Compared with leaf spring, the flexibility of spiral spring is much better, but the suspension structure becomes more complicated. As mentioned above, the leaf spring has the function of wheel positioning, while the coil spring does not. Therefore, we need to add some tie rods to force the wheels to stay in place. With the popularity of coil springs, independent suspension has gradually become the mainstream of passenger cars. The combination of independent suspension and spiral motion has almost become synonymous with sincerity and friendship in the industrial field. However, human beings' pursuit of comfort is endless. People are slowly beginning to discover the shortcoming of spiral spring: it is constant stiffness. In fact, it is the same as leaf spring: in the industry with leaf spring, it will bump when empty, but after loading heavy objects, the vehicle will become more flexible. In fact, the same is true of spiral springs: if the spring is too soft, it will be very comfortable when it is empty, but when it is overcrowded, the industry will collapse directly; If the spring is too hard, people everywhere will be very comfortable and the empty car will be very bumpy. Is there any way to solve this contradiction? The answer is yes, scientists have invented a miracle: the air spring. The air spring is actually a rubber airbag. It becomes elastic when it is filled with air. You can imagine it as a balloon. The higher the inflationary pressure, the more difficult it is; The lower the inflationary pressure, the softer it is. The reason is the same as the tire. It can be said that this is the gospel of mankind. The inflation should be reduced when the car is empty, and increased when it is fully loaded, so as to ensure that the spring always keeps the best comfortable state.
