Simulation Testing Research on Ride Comfort of Vehicle with Global-coupling Torsion-Elimination Suspension

Abstract A new-type suspension was built to even the vertical loads of each wheel effectively, reduce the torsion of vehicle body and improve the wheel ground adhesion. In order to study the influence of vehicle ride due to the structural change of suspension, road spectrums for vehicle ride simulation tests is constituted. Then performs ride simulating tests under the pulse input and random input with ADAMS. The simulation results reveal that the ride performance of vehicle with torsion-elimination suspension is also the same as that of original vehicle. This indicates that the torsion-elimination suspension will not bring worse effects to the ride comfort of vehicle.
