| 摘 要： | 对轮轨接触几何计算的迹线法进行了深入研究,给出了两种常用坐标系下‘迹线法’的正确计算公式.在此基础上,对轮轮接触几何关系进行了分析,结果表明:轮轮接触点计算并不能像轮轨一样缩减为一维搜索,只能由二维搜索得到,给出了一种简洁的轮轮接触二维搜索算法及公式；同时提供了一种快速搜索轮轨和轮轮接触点的编程方法.

| Abstract: | Based on the further study of "trail-method" of wheel rail contact,the correct calculation expressions under two kinds of common coordinate frames were proposed in this paper.Based on this basement,geometrical relationship of wheel-roller contact was analyzed.Results show that the calculation of wheel-roller contact point cannot be reduced to single dimensional searching as the calculation of wheel-rail contact point and it can be get by 2D search only,then the concise 2D search method and expressions were proposed;the new programming method of quick searching contact point of wheel-rail contact and wheel-roller contact was provided at the same time. |
