The straddle-type monorail train bogie has unique structures, whose operation, guiding mechanism and contact relationship between the wheel and rail are unusual. Domestic and foreign scholars have conducted a lot of researches on the modeling of dynamics of monorail train and vibration response characteristics, but there were few systematic conclusions. In view of the existing research results, this paper summarized the research methods of dynamic model of straddle-type monorail train and vibration response characteristics and relevant in- fluencing factor. Finally, the research priority in the future was proposed.
