为什么汽车减振器采用橡胶气囊来吸收冲击？

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

   其结果如下：

   The results are as follows:

  （1）它具有非线性特性，因此可以设计成理想的曲线。

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

  （2）橡胶安全气囊减振器有利于各种结构要求的应用。空气弹簧的工作高度可以在任何载荷下保持，在相同的载荷下，弹簧的高度也不同。

   (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）吸收高频振动和隔音的性能良好。

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

  （4）橡胶气囊的刚度随载荷的变化而变化。因此，该装置在任何载荷下的固有振动频率都是不变的，因此该装置具有几乎不变的性能。

   (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）橡胶气囊的刚度可以根据需要通过改变附加气室的容积来选择，而且选择很低。

   (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）空气弹簧的橡胶气囊体与附加气室之间设有节流孔，起到阻尼作用。如果孔径选择合适，则不能安装减震器。

   (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）相同的空气弹簧橡胶气囊既能同时承受轴向和径向载荷，又能同时承受传递力矩，并能通过调整内压获得不同的承载能力，从而能够满足多种载荷的要求。

    (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.
