Based on the steel wheel bending fatigue bench test, the bending fatigue life FEA model for the wheel was established. The wheel fatigue regions got in FEA analyses matched the actual test results well. The works established a foundation for further study on wheel fatigue use FEA and provided a basis for the steel wheel's design and manufacture, which also can enhance the products reliability and...
A three-dimensional model of bolster of heavy haul freight train was set up in the ANSYS11.0 according to the Codes of AAR M-202-05, the stress distribution of the casting bolster was calculated and analyzed. The result shows that the fatigue strength of the bolster was adequate and the relative weak point was found out. On the basis, the actual measurement test of entire car when it was running on...
