摘要
介绍了道岔区动力响应的模拟方法，重点考虑了道岔区几何尺寸与钢轨踏面的复杂变化，对轮轨接触采用了离散点精确描述与线性插值相结合的综合处理方法，建立了全车模型，分析了高速条件下道岔的动力响应。
This paper describes a method for simulating the dynamic behavior of a vehicle passing a turnout. Emphasis is great variation of geometry and rail tread in turnout zone.The wheel/rail contact geometry information is obtained from exact description of wheel/rail profiles at a series of track locations and linearly interpolating description at points betweenthese,locations from adjacent locationfiles,A detniled vehice model is estallished to analyze the dynamic behavior of No. 18 turnout for high-speed railways.
