Rail Grinding Technique and Its Application in High-Speed Railway

  • On the basis of formation and development characteristics of oblique rail cracks in Guangzhou-Shenzhen railway line,the rail asymmetrical grinding was used to prevent and decrease the appearance of oblique cracks.A field grinding test and numerical calculation were carried out.The calculated results show that the rail asymmetrical grinding has an effect on wheel-rail contact parameters,makes the wheel-rail contact point move from the shoulder of rail to the center of rail top surface,and decreases wheel-rail contact stress.The field grinding test has proven the above calculated results.The field test results indicate that the rail asymmetrical grinding can change the contact zone of wheel and rail and make the contact point move toward the center of rail tread.
