Abstract
This paper presents the experimental study of the torsion test and camber test of a flat freight wagon. The freight wagon considered as open-type 40 ft. gauge flat wagon. The flat freight wagon comprises flat body structure and two bogies, where the flat surface used to transport containers, goods, wood logs, etc. HBM load cell of 50 T capacity is used to measure the force and deflection for experimental determination of the torsional and camber values. The test methodology and setup are established freight wagon testing. It is seen that the camber values are within the safe zone as per designed payload. The average torsional stiffness is 3.45 × 1010 KN mm2/rad are seen considering the worst-case elevation with one side 20 mm and other three side elevations are zero.
