摘要
研究车轮在钢轨上的运动是确保铁路运输安全、高效的基本前提，通过编程计算出轨道不平顺处的钢轨底部弯曲应力，为预测钢轨的疲劳寿命提供了理论依据．
Research on the wheel sets locomotion over railways is the prerequisite of transportation security and efficiency. This paper gives theory foundation to forecast railway weariness life span through the calculation of railway bending stress.
