空气弹簧具有变刚度特性，其固有振动频率要比钢板弹簧低得多，且不随汽车承载质量的变化而改变。

Air spring is characteristic of variable stiffness, its natural vibration frequency is much lower than that of leaf spring and will not change with load of vehicle.

然后根据分析结果，以驾驶室不同载荷工况下的承载力为条件，为商用车驾驶室悬置选择合适的空气弹簧。

And then, choose the appropriate air spring for the vehicle cab mounting based on load at different load conditions and special conditions according to result.
