Dynamics study in high-speed running of central pin assembly of the dynamics stability vehicles

Combined with finite element software ABAQUS/Standard, the dynamic response of center pin assembly system on high-speed running is analyzed, which using interaction nonlinear numerical method. The result reveals that with the increase of running speed, contacting force increase and on the other hand, maximum stress, maximum strain and maximum displacement all decrease. This paper provided theoretical basis for improving and perfecting of the center pin assembly system and lay theoretical foundation for the further research of the dynamic stability vehicles.
