使用TSC-1M-4型应力集中磁指示仪测量在不同载荷下钢轨表面磁场强度的变化,得出钢轨的磁场强度随载荷的增加而逐渐增大,且在弹性范围内,磁场强度和载荷为近似线性关系。提出金属磁记忆法可以对钢轨内应力进行定量测量。
Using TSC-1M-4 stress concentration magnetic indicator to measure the magnetic field strength of rail surface under different loads, the magnetic field strength of the rail increases with the increase of load, and in the elastic range, the magnetic field strength and load are Approximate linear relationship. It is proposed that the metal magnetic memory method can quantitatively measure the stress in the rail.
