A FSAE racing car's model of double wishbone independent front suspension and steering system was built in ADAMS/CAR.The kinematics simulation was done by using parallel wheel travel analysis.The simulations was done again after the ball hinge of the lower control arm moved up and down respectively.The influences of front wheels alignment parameters were obvious when the position of the ball hinge of the lower control arm charged.%借助ADAMS/CAR,对某FSAE赛车双横臂独立前悬架和转向系统建立多体动力学模型,并对其进行前轮同向跳动仿真,对下控制臂球头铰上移和下移后再次仿真.仿真结果表明,下控制臂球头铰位置的变化对前轮定位参数影响显著.
