摘要：本文建立了列車單輪傳動模型，利用數(shù)學(xué)方法得到電機(jī)輸出轉(zhuǎn)矩和輪軌粘著在頻域上的關(guān)系，以CRH5型動車組所采用電機(jī)為例，研究其在SVPWM調(diào)制策略下的轉(zhuǎn)矩脈動，以及這些脈動對輪軌粘著的影響。 關(guān)鍵詞：調(diào)制策略；轉(zhuǎn)矩脈動；輪軌粘著 Abstract: This paper established the single wheel drive train model; Mathematical methods are used to get the motor output torque and the relationship between the wheel/rail adhesion in frequency domain; To type CRH5 emu adopted by motor as an example, studies the SVPWM modul[登陸后可查看全文]
