基于天棚和地棚混合阻尼的高速车辆横向减振器半主动控制

在研究抑制高速轨道车辆横向振动时，传统天棚阻尼控制方法使车体的横向振动降低的同时，却增加了转向架和轮对的横向振动，这样就导致机车高速运行时脱轨的可能性变大，运行安全性降低。针对上述问题，在Adams/Rial中建立了轨道车辆单节拖车的整车模型，利用Matlab/Simulink工具，结合天棚阻尼控制和地棚阻尼控制特点，研究了混合阻尼控制对高速列车横向振动的抑制作用。结果表明，混合天棚阻尼控制综合考虑了高速车辆运行时的舒适性和安全性，使高速车辆具有更好的综合性能。

Semi-active control method for a high-speed railway vehicle lateral damper based on skyhook and groundhook hybrid damping

In studying of the attenuation of high-speed railway vehicle lateral vibration, traditionnl skyhook damping control methods are designed to reduce body vibration. Althoughtt the vehicle lateral vibration is reduced , the bogie and wheelset lateral vibration increases, which may lead to vehicle derailment when the vehicle running at a high speed,the operation safety is also reduced. In order to solve the problem above, A single trailer vehicle model was established in the Adams/Rial.Combining the skyhook control with groundhook damping control,the mixed damping control was applied to reduce locomotive body lateral vibration. The results show that, mixed damping control consides both the high-speed railway vehicle comfort and safety, having better comprehensive performance.
