By obtaining the rail vertical force of the elastic rail fastener track through field tests, this paper verifies the results of the theoretical analysis.

Based on the extended homogeneous capacity precision integration method,a novel method was presented for solving plane bending problems of elastic arches with arbitrary profile.

On the basis of the strengthening and toughening mechanisms of low carbon martensite,low carbon alloy steel is used to replace medium carbon spring steel in order to produce type Ⅰ fastening elastic rod.
