Modeling methods of different models.

Models	Modeling method
Single particle model	Regard the train as a whole as a particle.
Multiparticle model 1	According to the four-motion and two-drag grouping mode, each power car is regarded as a particle.
Multiparticle model 2	According to the fact that there are two switch machines in each power car to control four moving wheelsets, each wheelset is regarded as a particle.
