摘  要：為了對(duì)直線電機(jī)轉(zhuǎn)向架結(jié)構(gòu)進(jìn)行分析，建立3種轉(zhuǎn)向架結(jié)構(gòu)形式的直線電機(jī)地鐵車輛動(dòng)力學(xué)模型。從車輛直線運(yùn)行穩(wěn)定性、運(yùn)行平穩(wěn)性和曲線通過(guò)安全性3個(gè)方面，對(duì)比分析3種結(jié)構(gòu)下地鐵車輛的動(dòng)力學(xué)性能。以期為直線電機(jī)車輛的更好運(yùn)用打下堅(jiān)實(shí)的基礎(chǔ)。

關(guān)鍵詞：直線電機(jī)；地鐵車輛；旁承摩擦力元；動(dòng)力學(xué)性能；轉(zhuǎn)向架結(jié)構(gòu)

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
