Abstract： In order to analyze the structure of linear motor bogies， the dynamic models of metro vehicles with three kinds of bogies are established. The dynamic performance of metro vehicles under three kinds of structures is compared and analyzed from three aspects： straight-line running stability， running stationarity and curve passing safety. In order to lay a solid foundation for the better use of linear motor vehicles.

Keywords： linear motor; metro vehicle; side bearing friction element; dynamic performance; bogie structure
