A numerical solution of the wave equation for torsional impact of a shaft which contains a single step and a rigid body at one end is found using the method of characteristics. The results are based on discontinuous stresses and elementary wave theory at the step. An experiment verified the predicted results, but showed that the actual impact stresses will always be slightly less since they are not discontinuous, as assumed. Some qualitative and quantitative generalizations are made concerning the expected maximum impact stress. |
