The obstacle (the altitude of 900 mm) process for both sides of a planetary gear train was analyzed in ADAMAS. It is proved that the physical dimension of the planetary gear train, bodywork center position and attachment coefficient are the key effect factors.

Another weaker pulse occurred when the rear wheel began climbing, and then the parameters reached a plateau.
