Abstract: Aiming at to solve the problem of including significant wear of front wheels caused by major sideslip and vulnerability to fracture of the steering tie rods,in the running test. A virtual prototype model with optimized suspension and steering systems was built in the ADAMS/Car module, and the methods of multibody kinematic analysis and multi objective optimization and design experiments were employed to tackle the problems and optimize the suspension and steering systems of the original ATV. The results indicate that after optimization of the vehicle has greatly improved in tire wear and handling stability . the vehicle under the condition of mount and non mount of stable performance are compared.

 

Key words: all terrain vehicle (ATV); automatic dynamic analysis of mechanical systems (ADAMS); suspension; steering system
