AlgorithmforWheelRailContactGeometry
- 提出并实现一种轮轨接触几何算法,可以检测铁道车辆系统动力学仿真在线计算时轮对与钢轨的刚性 单接触斑、多接触斑和跳离情形. 所得刚性接触斑可以为Hertz 理论提供刚性穿透量和曲率,为非Hertz 理论提 供接触区域的法向间隙,为动力学仿真提供接触中心位置和法向方向. 轮对与钢轨的计算机三维图形显示表明 该算法是有效的. 该算法已用于开发空间耦合的铁道车辆系统动力学仿真软件-Algorithm for Wheel Rail Contact Geometry

- 切片法求轮轨接处，使用的lm型车轮踏面和r60钢轨进行求解三维轮轨接触-Sectioning seeking the wheel-rail contact point, use lm-type wheel tread and rail r60 to solve the three-dimensional wheel-rail contact
WR_contactpoint_seek
- 求解轮轨接触点，首先得到车轮和钢轨的空间运动姿态，然后通过最小距离搜索轮轨接触点(In order to solve the wheel rail contact point, the space motion attitude of wheel and rail is first obtained, and then the wheel rail contact point is searched by minimum distance)
迹线法（钢轨与车轮接触点计算）
- 根据车轮与钢轨的接触点，采用迹线法，预测后期节点位置(According to the contact point between wheel and rail, the trace method is used to predict the later node position)
轨道频散曲线
- 将铁路视为周期结构，通过声子晶体的传递矩阵法，计算的钢轨的横波和纵波的色散曲线。两程序分别将钢轨视为欧拉梁和Timoshenko梁。(Regarding the railway as a periodic structure, the dispersion curves of the transverse and longitudinal waves of the rail are calculated by the transfer matrix method of phononic crys
