This paper firstbuilt the smi plemodelbased on the planned sketch of balance suspension, and relate optmi ization purpose function to design parameters, and optmi ize design variables using MATLAB language. Then, and the dynamic model of this equilibrium suspensionw ith the optmi ization results above in ADAMS/V iew. After smi ulating and verifying this design. The results prove that the structure canmeet the requirements of load distribution. ey words: A ll terrain vehicles; Doublew ishbone balance suspension; ADAM S smi ulation , , 1 (A llT errain Vehicle) 3, , , , 1, L , , , , , , , , , [ 1] 3 8 t [ 2] 7,
