摘　　要：分别基于动力吸振器理论与隔振理论,对高速列车车下设备弹性吊挂进行减振设计。建立了精细化车辆刚柔耦合动力学模型,基于该模型,对比研究了车辆运行且车下设备工作条件下,采用两种减振设计方案时车体与车下设备的振动特性。结果表明,采用弹性吊挂可以明显减小车体振动。相比基于隔振理论的减振设计而言,基于动力吸振器的减振设计降低车体弹性振动的效果更优,但一定程度上会增加车下设备的振动;而基于隔振理论的减振设计可以同时减小车体和设备的振动。在进行车下设备减振设计时,应根据具体要求选择合适的减振设计方法。The vibration reduction design of the equipment under high speed railway vehicle based on dynamic vibration absorber theory and vibration isolation theory was presented respectively. A detailed rigid-flexible coupled dynamic model of railway vehicle which includes the excitation of the suspended equipment itself was established. The difference of vibration properties of both car body and suspension equipment with the two kinds of design methods were studied on the condition that equipment was working and the vehicle was running. Results show that the use of elastic suspension can effectively decrease flexible vibration of car body. Comparing with vibration isolation theory, the method based on dynamic vibration absorber theory is more effective for suppressing car body flexible vibration, but it will increase the equipment vibration to a certain extent. The method based on vibration isolation theory can re- duce vibration of both car body and equipment at the same time. Therefore, the design method should be selected ap- propriately according to the specific requirements.
