| Abstract: | According to a in wheel motor driving electric vehicle assemblied with double wishbone suspension with torsion bar,the mathematic model of suspension is built,in which the structure features,the dimensions and the gestures of the bars,the springs and the dampers are considered.With the mathematic model of the suspension,the 1/4 vehicle model is also built.Based on this model,the structural nonlinearity is researched,and the vehicle performances especially vertical performances are discussed considering the structural nonlinearity.This research method brings the suspension damping and stiffness match into nonlinear field,which advances the deactive suspension development theory. |
