Influence of Primary Spring Stiffness on Strength of C0 Bogie Frame

  • In order to determine the reasonalbe stiffness of middle-axle primary spring,the distribution of stresses in C0 bogie frame was investigated with FEM(finite element method) based on two kinds of boundary conditions,i.e.,spring constraint and force constraint.The influence of middle-axle primary spring on stresses of partial key nodes was analyzed under different vertical curves and vertical stiffness.In addition,the re-distribution of stresses in C0 bogie frame was discussed.The numerical result shows that the constraint conditions in a finite element model for C0 bogie frame must ensure that the three axles have the same mass,and a reasonable distribution of stresses in C0 bogie frame can be obtained when the vertical stiffness of middle-axle primary spring is smaller than that of the two end-axles.
