摘　　要：准静态轮轨关系是指在连续光滑条件下的轮轨接触几何和作用力关系,但轮轨接触"磨光"处理一般要采用加权平均的数值方法,即所谓准弹性接触。考虑到轮轨接触非线性和转向架自身非线性都将对轮轨接触产生影响,因而准静态轮轨关系的应用必须慎重,如高速转向架要有比较充足的稳定性裕度。双振子频响和频谱分析以及整车线性稳定性分析等3个对比与验证表明新型分析软件在线性系统分析应用方面具有极大的灵活性,轮轨蠕滑力计算更加接近实际,这为高铁车辆(HSRS)研发提供了非常好的应用平台。The quasi-static W/R interaction is the W/R contact geometrical relation and interaction under the continuity and smoothness conditions,which is ＇polished＇ generally by the numerical method of weighted mean value,that is,the quasi-elastic contact.Since the W/R interactions can be influenced by both non-linearity of W/R contacts and bogies themselves,it should be careful in the application of the quasi-static W/R interaction,for example,the high-speed bogie with the more sufficient stability margin.In the three contrasts or validations,i.e.,the frequency responses and spectra analyses of double oscillators and the linear stability analysis of full vehicle,it is shown that the flexibility of the linear system analysis applications is presented extremely and the W/R creeping calculation is approached to the reality in the newly-type analysis software,which is very suitable application platform for High-speed Rolling Stocks（HSRS）.
