2.An ideal traction motive power for fast transportation of special goods DF_(8BG) diesel locomotives
3.Power car of 200 km/h electric passenger train -----A new jumping off point of high speed traction
4.： By comparing and analysing on the appearance, performance, maintenance, running cost and gains between type SS9 locomotive and type DJ locomotive, the author points out the weakness of DC－drive and puts forward that AC－drive is the trend of railway traction development．
6.Through analysis of the characteristics, structure and parameter of 3 -phase asynchronous traction motor,in regard to its specific role as traction power in locomotive, the author put forward the problems that with the same slip ratio, in low frequency stage, the output torque of motor goes down and the mechanical characteristics become "soft". Theoretically,the auther analyses the cause for the problems and airs his view on these two problems.
7.Motor train unit(EMU), which incorporating traction power and carrier, is the train traveling on special railway line. Mode of train operation organization is "Less group, High density", which ensure transportation on special line just like public traffic, and stand out the preponderant competition in passenger transportation market.
8.Test shows the tr action converter fully satisfies the requirements by power distributed AC drive EMU.
10.Model JD112 asynchronous traction motor for type DJF_1 drivi ng force scat tered AC EMU
