The theory was validated by experiment. The experimental study involved direct strain-gage measurements in the contact area of the rolling cylinders. The state of strain in the wheel/rail contact region was studied. Contact region stress distributions for various relative positions of the wheelset with respect to the rail track were determined. Angles of attack were accounted for. The computational results were used to design improved contours of wheel tread and rail head. 1 Introduction A study into wheel/rail contact interaction should include an analysis of the state of stress at
