Abstract: The virtual contact loading method is further developed in this paper to simulate the contact phenomena on the interference fitting surfaces between wheel hub and shaft. A new algorithm is proposed to solve the three-dimensional contact stress distributions in a wheel-shaft pair, where the fitted shaft and wheel are subjected to the typical vertical and horizontal loads. The influence of some structural parameters, interference tolerance and structural geometry, on the contact stress distribution has been studied in more detail and some reasonable results are obtained.

Keywords: fitting stress; numerical computation; rail vehicle; shafts; interference fitting surfaces; wheel hubs; virtual contact loading; simulation; contact stress distribution; structural parameters; interference tolerances; structural geometry.
