Modeling and simulation of the guide rod tandem suspension model

The guide rod tandem suspension was divided into rigid parts and flexible parts by the analysis and simplification of its structure. In ADAMS, the model of rigid parts was built, and the model of flexible parts was built by the discrete beam element method. A integrated dynamic model of the guide rod tandem suspension was assembled by reasonable constraints between rigid parts and flexible parts. In order to validate the model, road vertical displacement motion actuators of four wheels were applied to simulate parallel wheel travel, pitch, roll and pitch-roll cases of the guide rod tandem suspension, the motion tracks of the suspension for four cases validated the reasonability of model.
