The simulation analysis of the centroid offset effects on braking performance

In order to study centroid offset of the vehicle affects on the braking performance and the longitudinal and horizontal offset of the centroid affects on the stability, it analyses theoretically the relation between centroid position and braking performance. And it establishes the whole vehicle's model through simulation soft ADAMS/CAR of the dynamics and analyses the relation between longitudinal offset and the rotate speed and between horizontal offset and heading angle; the same condition, it analyses that horizontal offset of the centroid affects on horizontal replacement and heading angle. The Simulation result indicates : while the centroid moves longitudinal and forward, lateral stability becomes worse and while the centroid moves backward can increase to braking stability, but it makes easily the front wheel lose the turning ability; while the centroid happens to horizontal offset and along with the offset gradually increase, horizontal replacement and heading angle increase notability. It the centroid can be controlled while the vehicle brakes may enhance security of the vehicle.
