Abstract
Design of traditional vehicles is lack of mechanism for changing lateral mass center position. The purpose of this research is to design a mechanism which the lateral mass center position can be changed to improve the cornering behavior of the vehicle. Before design an advanced concept vehicle with movable mass center, it is necessary to do theoretical analysis to find the design parameters. After theoretical analysis was completed, a mechanism was designed and manufactured. This mechanism was put on a real all-terrain vehicle and than carry out the road test. The results of analysis and the results of experiment have very good agreement. Besides the work of mass center moving mechanism, the framework of this all-terrain vehicle was modified, and the new shape of the vehicle was created.
