摘　　要：针对已有在悬架系统中研究油压减振器动力学模型的局限性,提出了一种分析减振器系统动力学问题的新方法.以KONI减振器为例,建立了KONI减振器系统动力学的模型,并对其进行了仿真研究.仿真结果表明,经过一段时间后,系统振动幅值逐渐衰减并趋于稳态,与输入激励在频率上一致.本文的结果可作为减振器改进和设计的理论依据,对于分析车辆运行平顺性具有指导意义,对于进一步分析和设计减振器提供参考依据.A new method is brought forward to analyze the dynamics problem of the suspension system,aiming at solving the limitation there has been for studying the dynamic modeling of hydraulic shock absorber in the suspension system. By way of illustration of KONI shock absorber, the modeling of shock absorber dynamic system is established, and the result of simulation is studied. It is demonstrated that system vibration amplitude gradually reduces to the steady condition after a period of time,coincided with input excitation on the frequency. The textual results can be used for the theoretical basis of improving and designing shock absorber, also they have the guidable significance to analyze the smooth ride of vehicle, and provide the referential basis for the further analysis and design of shock absorber.
