Abstract:

A vehicle body may bear a large twist load due to the uneven load on four wheels when the vehicle runs on rough road. In order to reduce the twist load, a new type of torsion-eliminated suspension structure is brought forward, and a simple mathematical model is established to explain the principle of torsion elimination. Moreover, a model of the vehicle with the suspension is constructed by using the multi-body dynamics simulation software ADAMS, and the abilities of torsion elimination and ground adhesion of the vehicle at various speeds are simulated. The results show that, when the vehicle runs at a low speed, the torsion-eliminated suspension is effective in reducing the twist load of vehicle body and in improving the ability of ground adhesion.

Key words: torsion-eliminated suspension, ADAMS, twist load, ground adhesion ability
