| Summary: | Based on the development and application of passenger car bogies in China, this paper analyzed the characteristics and shortcomings of the bogies of the existing technology platform. In addition, in order to enhance and improve the comprehensive service performance indexes of vehicles, the research on the key technologies of the bogies, such as bearings, wheels, axles and suspensions, for the speed level of 200 km/h was conducted. Based on the reference of the "CRH" and "Fuxing" EMU bogies, trailer bogies for new 200 km/h power centralized EMU were designed, and a strength simulation analysis of key stressed components, an evaluation of weld stress value and a verification of static strength and fatigue strength on test bench were made, which proved that the strength of bogies meets UIC, EN and TB standards. According to the multi-body dynamics modeling, simulation and analysis, the suspension parameters of the bogies are reasonable and all dynamic performance indexes can reach the superior level. |
