摘要
在对各种轮轨蠕滑计算模型进行归类分析的基础上，详细地讨论了Ｋａｌｋｅｒ 教授提出的ＵＳＥＴＡＢ 插值表法的结构和应用的可能途径，并对几种典型的方法作了分析比较。在Ｆｏｒｔｒａｎ ＰｏｗｅｒＳｔａｔｉｏｎ４ ．０ 的平台上实现了ＵＳＥＴＡＢ、ＦＡＳＴＳＩＭ，Ｊ－ Ｖ算法。结果表明不同模型之间的差异随不同的轮轨接触条件而变化。计算结果可以作为选择轮轨蠕滑模型的依据。
Various creep force models are discussed and classified according to their calculation methods. A newly invented method called USETAB by J J Kalker is illustrated especially. Some well known methods are compared with the USETAB.The result shows the varying differences with the different wheel/rail contact condition. A suggestion is given for the modeling of railway vehicles.
