Design Method for Rigid Frog Based on Wheel/Rail Contact Parameters

摘要

摘要: 为了更好地设计固定辙叉结构,改进轮对与辙叉间的相互作用关系,提出了以接触参数为基础的设计方法,并对60 kg/m钢轨12号固定辙叉心轨及翼轨顶面的各部位尺寸进行优化.结果表明:将此固定辙叉心轨顶宽20 mm处降低值增大至4 mm,取消翼轨顶面 1∶20 横坡,并将翼轨顶面抬高范围改为从辙叉咽喉至心轨顶宽50 mm处,可较好的改善其轮轨关系,验证了本文设计方法的可行性和有效性.

Abstract: A design method of rigid frog structure based on contact parameters was proposed in order to improve its wheel/rail interaction relationship. Using the method, the top profiles of nose rail and wing rail of No.12 rigid frog were optimized. The results show that the wheel/rail relationship can be improved effectively by lowering the height of the nose-rail section with the head width of 20 mm by 4 mm, eliminating the 1∶20 cross slope of the wing-rail head, and modifying the wing-rail head rising scope to be from the throat to the nose-rail section with the head width of 50 mm. Therefore, the proposed method is feasible and valid.
