| Abstract: | Taking the suspension device of the driving unit on permanent magnet direct drive electric locomotive bogie as the research object,strength analysis of the suspension device structure is carried out by using finite element analysis method.The sub-model of the area where the bolts are installed is established by intercepting the suspension device model.Static strength and fatigue strength of the bolts are mainly measured.The calculation results all meet the design requirements. |
