空气弹簧减震器的选用要求Selection REquirements of air spring shock absorber

    空气弹簧减震器是连接设备和基础的弹性元件，用以消除和减少由设备传递到基础的振动力，和由基础传递到设备的振动。使系统与稳态基础隔离的弹性支撑。激发频率低于质量(设备)弹簧系统的固有频率时，减震器不起隔振作用；激发频率与固有频率相近时，振动就会放大；只有当激发频率大于固有频率的2次方根倍时，减震器才有减振效果。通常要求激发频率大于固有频率的2～3倍，以便获得良好的隔振效果。

The air spring shock absorber is an elastic element connecting the equipment and the foundation, which is used to eliminate and reduce the vibration force transmitted from the equipment to the foundation and from the foundation to the equipment. An elastic support that isolates the system from the steady-state foundation. When the excitation frequency is lower than the natural frequency of the mass (equipment) spring system, the shock absorber does not play a role in vibration isolation; when the excitation frequency is close to the natural frequency, the vibration will be amplified; only when the excitation frequency is greater than the second root of the natural frequency, can the shock absorber have the damping effect. In order to obtain good vibration isolation effect, the excitation frequency should be 2 ~ 3 times of the natural frequency.

    减震器具体形式有：钢弹簧减振器、橡胶减振器、气垫弹簧、橡胶减振垫、阻尼弹簧减振器及各种复合式减振装置等。使用时要配备合适的设备支架。减振器型号及数量的选择既要保证能承受设备的动力荷载，又能保持小的传振系数(传递力与干扰力之比)。减振器设计和应用时。

The concrete forms of shock absorber are: steel spring shock absorber, rubber shock absorber, air cushion spring, rubber shock absorber, damping spring shock absorber and various composite damping devices. Proper equipment support should be provided when using. The selection of the type and quantity of the shock absorber should not only ensure that it can bear the dynamic load of the equipment, but also keep a small vibration transmission coefficient (the ratio of transmission force to interference force). When the shock absorber is designed and applied.

    我们的减震器对汽车的保护非常重要，所以当谈到舒适性时，我们自然会想到减震器。如何测试减震器，以及如何操作它？首先，在行驶条件较差的道路上行驶约10公里，停车后触摸空气弹簧减震器壳，如果感觉不到热量，可以先添加适当的润滑剂，然后进行测试。如果外壳是热的，那么你不用担心，因为减震器内部没有油，只要油足够，就可以了。否则，减震器会失效。还有两种快速检测方法，如慢速汽车突然紧急制动，如果汽车振动更强烈。这证明减震器出了问题。用力推保险杠，然后再次松开。如果汽车有2-3次跳跃，减震器状况良好。

Our shock absorbers are very important for car protection, so when it comes to comfort, we naturally think of shock absorbers. How to test the shock absorber and how to operate it? First, drive for about 10 km on the road with poor driving conditions. After parking, touch the air spring shock absorber housing. If you can't feel the heat, you can first add appropriate lubricant, and then test it. If the shell is hot, then you don't have to worry, because there is no oil inside the shock absorber, as long as the oil is enough, it is OK. Otherwise, the shock absorber will fail. There are also two fast detection methods, such as the sudden emergency braking of a slow car, if the vehicle vibration is stronger. This proves that there is something wrong with the shock absorber. Push the bumper hard and release again. If the car has 2-3 jumps, the shock absorber is in good condition.
