以客运专线18号道岔为例,选取磨耗型踏面车轮,建立弹性基底约束条件下的道岔区转辙器部分轮轨接触计算模型,对尖轨轨头顶宽20~50 mm范围内轮载过渡区,尖轨及基本轨的轮轨接触应力进行了较为详细的分析。
Taking the 18th turnout of Passenger Dedicated Line as an example, the model of wheel-rail contact of turnout in turnout area under the constraint of elastic foundation is established by selecting the wear-type tread wheel. The wheel-carrier transition zone of 20-50 mm , The rail and the basic rail wheel rail contact stress conducted a more detailed analysis.
