摘要：
In the paper, Assessment and comparison analyses of fatigue strength for different axles of CRH2, CRH3 and CRH5 EMUs are conducted by applying the European standards and Japanese standards. The wheelset models of CRH2, CRH3 and CRH5 are set up by means of the finite element method. Static and fatigue strength of the axles are analyzed as well as the influence of the interference fit between wheel and axle on the contact pressure. To get accurate simulation of the dynamic loads on axles, mathematical models of CRH2, CRH3 and CRH5 EMUs are established by using the SIMPACK software, considering the nonlinearities in the EMU vehicle systems. The simulation is carried out according to the runtime table of the EMU in Beijing-Tianjin line. Stochastic irregularities of the track are considered in the dynamic simulation and the load history acted on wheelset is obtained. Based on the NSOFT software, the fatigue life of axles is predicted by applying appropriate fatigue life prediction methods.
