摘要
在动力学试验中发现同一类型的变阻尼转向架具有不同的动力学性能。通过建立动力学模型,应用统计分析的方法,得出转向架尺寸制造误差导致减振力变化是造成转向架动力学性能存在差异的主要原因,并给出了相应的建议。
It is found out in dynamic tests that variably damped truck of the same type has different dynamic performances. By setting up a dynamic model and using statistical analysis, it was found out that the main reason was the variation in snubbing force due to tolerance in the truck＇s manufacture, and the corresponding advice is given.
