根據(jù)流體力學(xué)理論，空氣彈簧節(jié)流孔的流量特點(diǎn)：
According to the theory of fluid mechanics, the flow characteristics of air spring orifice:
1、空氣的密度；
1. Density of air;
2、經(jīng)過空氣彈簧節(jié)流孔的空氣質(zhì)量；
2, through the air spring throttle hole air quality;
3、空氣彈簧節(jié)流孔面積；
3, air spring throttle hole area;
4、空氣彈簧節(jié)流孔的流量系數(shù)；
4, air spring orifice flow coefficient;
5、附加空氣室與空氣彈簧本體之間壓力的變化量。
5. Variation of pressure between the additional air chamber and the air spring body.
節(jié)流孔的流量與壓力差存在非線性關(guān)系，為得出系統(tǒng)的阻尼特性，故需對其進(jìn)行線性處理，則有：
There is a nonlinear relationship between the flow rate of the orifice and the pressure difference. In order to obtain the damping characteristic of the system, it is necessary to conduct a linear treatment on it, then:
帶附加空氣室空氣彈簧的力學(xué)模型，對于節(jié)流孔產(chǎn)生阻尼效應(yīng)的空氣彈簧，等效于一個(gè)具有彈性支撐的減振器系統(tǒng)，即剛度為的空氣彈簧與阻尼系數(shù)為的減振器并聯(lián)，再與剛度為的空氣彈簧串聯(lián)，最后與剛度為的空氣彈簧并聯(lián)。
The mechanical model of air spring with additional air chamber is equivalent to a shock absorber system with elastic support for the air spring with damping effect generated by throttling hole, that is, the air spring with stiffness is connected in parallel with the shock absorber with damping coefficient, and then is connected in series with the air spring with stiffness, and finally is connected in parallel with the air spring with stiffness.
