| 摘 要： | 本文从摩擦、接触理论与断裂力学方面论述了轴重与钢轨磨耗和损伤的关系,并结合现场的调查资料与实际情况,提出钢轨磨耗与破损和轴重成指数关系而与运量成比例关系的结论。为适应我国重载运输的需要和轴重不断提高的趋势,对轨道与转向架结构提出了改进建议。

| Abstract: | In light of tribology,contact theory,and fracture mechanics,this article deals with the relation of axle load to rail wear and rail fail ure,and conludes,by taking consideration of practical situation and data of field investigation,that the rail wear and rail failure is an exponential ruction of axle load and proportional to the traffic volume. In order to meet the need of heavy loading transportation and the trend of unceasing growth of axle load in our country,a suggestion for impro- ving track construction and bogie structure is proposed. |
