| Abstract: | With the rigid dynamics analysis model of vehicle, a calculation of loading time course of a 209HS framework passing through a turnout straightly is carried out by the Newmark method. After building the finite element model and compiling the log files, the transient dynamic analysis module of the ANSYS software is adopted to calculate the dynamic stress of the 209HS framework. The result proves it's feasible to carry out a practical dynamic stress analysis of the framework. |
