   為什么汽車減振器采用橡膠氣囊來吸收沖擊？

   Why do car shock absorbers use rubber air bags to absorb shocks?

   其結果如下：

   The results are as follows:

  （1）它具有非線性特性，因此可以設計成理想的曲線。

   (1) it has nonlinear characteristics, so it can be designed as an ideal curve.

  （2）橡膠安全氣囊減振器有利于各種結構要求的應用。空氣彈簧的工作高度可以在任何載荷下保持，在相同的載荷下，彈簧的高度也不同。

   (2) rubber airbag shock absorber is conducive to the application of various structural requirements.The working height of the air spring can be maintained under any load, and the spring height is different under the same load.

  （3）吸收高頻振動和隔音的性能良好。

   (3) good performance in absorbing high-frequency vibration and sound insulation.

  （4）橡膠氣囊的剛度隨載荷的變化而變化。因此，該裝置在任何載荷下的固有振動頻率都是不變的，因此該裝置具有幾乎不變的性能。

   (4) the stiffness of rubber air bag changes with the change of load.Therefore, the natural vibration frequency of the device under any load is constant, so the device has almost constant performance.

  （5）橡膠氣囊的剛度可以根據需要通過改變附加氣室的容積來選擇，而且選擇很低。

   (5) the stiffness of the rubber air bag can be selected by changing the volume of the additional air chamber as required, and the selection is very low.

  （6）空氣彈簧的橡膠氣囊體與附加氣室之間設有節流孔，起到阻尼作用。如果孔徑選擇合適，則不能安裝減震器。

   (6) a throttle hole is arranged between the rubber air bag body of the air spring and the additional air chamber to play a damping role.Shock absorbers cannot be installed if the aperture is chosen correctly.

  （7）相同的空氣彈簧橡膠氣囊既能同時承受軸向和徑向載荷，又能同時承受傳遞力矩，并能通過調整內壓獲得不同的承載能力，從而能夠滿足多種載荷的要求。

    (7) the same air spring rubber air bag can bear both axial and radial load, but also bear the transfer torque, and can obtain different bearing capacity by adjusting the internal pressure, so as to meet the requirements of a variety of loads.
