摘要
基于动力吸振器的工作原理,探讨了将车下设备设计成动力吸振器以降低车体振动的可行性,并以某高速列车和其车下设备为例,分析了调谐比和阻尼比对位移传递率的影响规律,得到了动力吸振器的弹性阻尼参数,设计了弹性阻尼元件。
On the basis of the working principle of dynamic vibration absorber,the feasibility to design the equipment under train into the dynamic vibration absorber is discussed to reduce the vibration of carbodies.Furthermore,with a certain high speed train and its equipment under the train as the example,the regular pattern of the tuning ratio and damping ratio affecting the displacement transfer ratio is analyzed,the resilient damping parameters of the dynamic vibration absorber are obtained,and the resilient damping elements are designed.
