Light-weighting of high speed railway equipments has become a major trend, which leads to the upgradations of equipments. A new C-shaped bracket has been produced to connect the driving gearbox with the bogie. This paper built a three-dimensions model of a C-shaped bracket, got the maximum distribution of the stress and deformation under two different working conditions from finite element analysis (FEA). Then it presents a method to perform a corresponding experiment. It is observed that the computed values form FEA are in very good agreement with the experimental values, which both verified the structural strength of this C-shaped bracket.
