The principles, structure and application effect of the non contact type automatic inspection equipment for wheel tread shape are described.
介绍车轮踏面形状非接触式自动检测装置的原理、结构组成及使用效果。
The wheel-rail contact geometry relationship is different when different wheel tread shape matches the same rail, which will influence the dynamic performance of the vehicle.
不同的车轮踏面形状与同一钢轨匹配时具有不同的轮轨接触几何关系，影响车辆的动力学性能。
The influence of train running speed, wheel-rail friction coefficient, vehicle load, track geometric irregularity, partly load, gauge and the shape of wheel tread on derailment was emphasized.
论文重点分析了车辆运行速度、轮轨摩擦系数、车辆载重、轨道几何不平顺、偏载、轨距大小、车轮踏面形状等因素对脱轨的影响。
The plastic deformation would more easily occur due to the impact contact, but it is independent to the shape of tread. However, to eliminate the irregularity between the wheel and rail is necessary.
碰撞接触容易引起塑性变形，这种变形与踏面形状无关，应注意消除轮轨间的不平顺。
