摘 要: 用有限元参数二次规划法来分析轮轨的接触问题,提出了研究轮轨关系问题的新方法;同时给出了用此方法计算轮轨接触区内力的结果,并指出了各接触点对的接触状态和受力情况. Analyses the wheel rail contact problem with the three dimension finite element parametric quadric program and provides a new method of studying the wheel rail ralationship. Gives the computation results of the contact innet force within the wheel rail contact region. And also points the contact state and stress distribution of each pair of contact points are also pointed out.
