Roll angle of sprung masses
Did you know?
WebWhen the roll center is high, the roll torque will be smaller, as a result, the body-roll angle increases consequently. If the roll center is too elevated can pressurize the wheel track when the body tilts, thus reducing the service life of tires. For FSAE racing, the roll center is kept low, so the sprung mass does not roll too much so that ... WebApr 24, 2024 · When the roll movement of sprung mass agrees with the assumption in Figure 2 (b), the deformations of one couple of hydropneumatic springs installed left and right on the vehicle are equal. Therefore, the roll angle can be derived as where is the distance between the supporting points of hydropneumatic springs and the vehicle …
WebRoll rate or Roll stiffness is defined as the resistance moment generated per unit of the roll angle of the sprung mass and is represented as KΦ = ( (a^2)*Kt)/2 or Roll rate/ Roll stiffness = ( (Track width of vehicle^2)*Wheel rate of vehicle)/2. WebThe vehicle sprung mass is considered a rigid body. Thus the angle of the sprung mass from the roll centre is the same all the way along the body. The roll centre height is not …
Webstiffness affects the handling and stability, therefore to avoid the tendency to roll over, the rear suspension roll angle stiffness is kept smaller than the front. When the roll center is … WebDec 23, 2024 · The results of the paper showed that the values of the roll angle, the difference in the vertical force at the wheels, and the displacement of the unsprung mass were significantly reduced when the vehicle used the active stabilizer bar, which is controlled by an intelligent control method.
WebSep 14, 2024 · Therefore, this paper considers the roll stability of heavy trucks while conducting path planning. To simplify the modeling process, some idealized assumptions are made for heavy trucks: 1. The pitch and the vertical motion of the vehicle are ignored. 2. The influence of side wind is ignored. 3. The effect of tire aligning torque is ignored. 4.
