THEORETICAL THERMAL STRESSES DEVELOPED IN RAILWAY CAR WHEELS BY THE DRAG TEST

The theoretical stress developed in four different design railway car wheels by a fifty horsepower thermal load is presented. The stresses developed were determined by the use of an elastic finite element analysis and the results are shown to be influenced by the geometric design of the wheel. Theoretical boundary conditions used for the particular study and the need for further analysis with different boundary conditions are discussed. Examination of the theoretical results for this specific thermal load show the following. 1. An increase in wheel diameter with no other geometric changes can cause a slight decrease in stress at the higher stressed region. 2. An increase in rim thickness definitely restricts the temperature developed in the wheel. The resulting stresses developed in the plate may be significantly lower. 3. Plate shape and location significantly influence the stresses developed.
