Analysis of Braking Stability of Rhombic New Concept Car

The dynamics model of rhombic new concept car in the brake process was established.The slid-displacement of the center of mass and course angle were obtained when the disturb force and disturb torsion acted on the center of the mass through matlab/simulink.Simulation results have indicated that the rhombic new concept car will be unstable if the rear wheel is locked before the front wheel when the middle wheel is locked,and the condition will be more acute when the rear wheel is locked first and alone.At last,ways to avoid unstable condition were given.Theoretical support for the design of the rhombic new concept car was proposed.
