本文总结了液力悬置的发展历史和结构种类，简单的介绍了各类悬置的物理模型，动态特性等，从流体力学的角度出发，通过对半主动液力悬置惯性通道内流体的动力学分析，建立了半主动液力悬置内部压力变化的运动微分方程，得到了流体在惯性通道内流动时产生的阻尼力表达式。从表达式中可以看出流体在惯性通道的阻尼力与流体的速度、通道截面积、通道长度、流体所选用的材料的特性和激振力有关。
通过分析半主动液力悬置的结构和工作原理，建立半主动悬置的物理模型和数学模型，并结合前文分析得到的阻尼力表达式，求解到半主动液力悬置的动刚度和动阻尼表达式。然后对液力悬置的动态特性进行了仿真，通过分析依次改变半主动液力悬置惯性通道管截面积S和长度l两个参数的大小后得到的动态特性仿真曲线，可以看出半主动液力悬置确实弥补了橡胶悬置低频阻尼不足，高频动刚度偏大的缺点。由此可以认为通过改变惯性通道截面积s来改变悬置动态特性，进而改变悬置的隔振性能是可行的。

This article summarized the fluid strength suspension development history and the structure type, simple introduction each kind of suspension physical model, dynamic characteristic and so on, follows the current the body mechanics angle to embark, through fifty-fifty the driving fluid strength suspension inertia channel in the fluid dynamics analysis, has established the semi-active fluid strength suspension internal pressure change movement differential equation, the damping force expression which obtained the fluid flows when the inertia channel produces. May see the fluid from the expression in the formula the material characteristic which in the inertia channel damping force and the fluid speed, the channel cross-sectional area, the passage length, the fluid selects and the strength related .
Through analyzes the semi-active fluid strength suspension the structure and the principle of work, establishes the semi-active suspension the physical model and the mathematical model
