209HS准高速双层客车动力学试验研究与分析

Study and Analyses of Dynamic Tests of 209HS Quasi High Speed Double Deck

通过对209HS准高速转向架一系列动力学试验的分析与理论研究的比较，证实了轴箱定位器由Ⅰ型改为Ⅲ型的有效性和部分旁承支重对抑制转向架蛇行运动的可行性。对该客车车体结构及转向架参数设计的合理性作一评价，并分析了在180km／h运行时平稳指标上升较快的原因，最后提出改进意见，为准高速客车设计提供参考。

By analysing and comparing a series of dynamic tests of the quasi high speed double deck with the model 209HS bogie, this paper proves that the model Ⅲ axle box locator is effective for improving the ride performance of the carbody and partial load of the side snug is feasible for restraining the hunting of the bogie. It also gives an evalution of the construction of the carbody and the parameters of the bogie, and analyses the reason that the ride index goes so rapibly when the speed of the train is up to 180 km/h. Finally, some practice proposals which can be referenced in designing high speed coaches are presented.
