The invention provides an anti-side-rolling variable stiffness method and anti-side-rolling device. The anti-side-rolling device comprises a pair of connecting rods, a pair of torsion arms and a pairof elastic connecting parts, the pair of connecting rods are connected with a vehicle body, the pair of torsion arms are each provided with three rotating connecting points, the rotating connecting points A are rotationally connected with the other ends of the connecting rods, and the rotating connecting points O are rotationally connected with a bogie, the two ends of the elastic connecting partare connected between the bogie and the rotating connecting points B, the two ends of the elastic connecting part are connected with the bogie and the rotating connecting points B in a rotating mode,the angle AOB formed by the three rotating connecting points is not equal to 180 degrees, and the anti-side-rolling rigidity is changed by adjusting damping of the elastic connecting part. The elasticconnecting part provides a damping effect for rotation of the torsion arm, and the rigidity of the whole anti-side-rolling device during vehicle side rolling can be changed by changing the damping coefficient of the elastic connecting part; and the torsion arms in the two sets of anti-side-rolling devices work independently, and the change of the rigidity of the torsion arms and the torsion angles of the torsion arms are not affected mutually during vehicle side rolling.
提供一种抗侧滚装置,包括一对连杆、一对扭转臂和一对弹性连接部件,令一对连杆分别和车体连接,在一对扭转臂上分别设置三个转动连接点,令转动连接点A和连杆的另一端转动连接,转动连接点O和转向架转动连接,将弹性连接部件两端连接至转向架和转动连接点B之间,弹性连接部件的两端和转向架、转动连接点B均为转动连接,三个转动连接点所形成的角度∠AOB≠180°,通过调节弹性连接部件的阻尼来改变所述的抗侧滚刚度。弹性连接部件为扭转臂的旋转提供阻尼作用,通过改变弹性连接部件的阻尼系数则可改变整个抗侧滚装置在车辆侧滚时的刚度。两组抗侧滚装置中的扭转臂是独立工作的,其刚度的变化以及车辆在侧滚时扭转臂的扭转角度均互相不受影响。
