摘  要:
设计了一种可控刚度阻尼的油气悬架,在对其结构和工作原理进行分析的基础上,建立了油气悬架非线性数学模型,通过理论分析、仿真与台架试验,表明所建立的数学模型正确可靠,蓄能器的工作总容积对刚度特性有明显影响、节流孔面积对阻尼特性影响显著。通过改变蓄能器连通数目的方法改变了蓄能器的工作总容积,从而系统的刚度特性也得到了控制;通过改变节流孔的大小来改变系统的阻尼特性非常有效。

摘  要:
A kind of hydro-pneumatic suspension with controllable stiffness and damping was designed. A complex nonlinear mathematic model of hydro-pneumatic suspensions was set up on the basis of comprehensive analysis of its working principle and structure. Simulation results comparison and theoretical analysis with the test data of bench test showed that the mathematic model is authentic. The volume of gas accumulator markedly affected the stiffness of hydro-pneumatic suspension, and the size of throttle notably affected the damping of the hydro-pneumatic suspension. The total volume of gas accumulator could be controlled by changing the number of gas accumulators, and the stiffness of hydro-pneumatic suspension could be controlled further more; the damping of hydro-pneumatic suspension could also be controlled by changing the size of throttle.
