For this purpose, a new approach is being pursued to describe the tire contact patch by the use of a super ellipse. Furthermore, the calculation of the pressure distribution is developed within this contact area. A regression model is used to identify the model parameter's sensitivity to the...
The calculation of the vertical force Fz acting at point P in the tyre contact patch has a contribution due to stiffness Fzk and a contribution due to damping Fzc. These forces act in the direction of the {Zsae}1 vector shown in Figure 5.18 Sign in to download full-size image FIGURE ...
Considering the inverse relationship between the real contact area and the contact stress, the texture influence coefficient θ is defined as the ratio of the real contact patch of tire-pavement under the standard pavement texture to the real contact patch of tire-pavement under the current ...
calculation of these forces, the following assumptions are made within the model. The normal contact pressure along the entire length of the tire patch is treated as a constant. Its value is F z /x p , with F z calculated in the manner described in Section 2.2. x p is estimated...
These are mainly due to the non-uniform distribution of the data points over the slip angle, camber and load area and the mutual dependency in between the slip angle, camber and load. A new MF model for pure cornering slip conditions has been developed that allows the calculation of the ...
13 17 3 The puncture injury is 1/4 inch (6 mm) or less and must be within the tread area as shown in the graphic. This helps ensure long-term tire and repair durability. 3 A patch is applied to the interior of the tire and the puncture hole is filled with a suitable plug/stem ...
Counteracting these forces is the load of the vehicle which is only supported in the small area of the tire known as the contact patch. Current tire design drivers are an aircraft tire capable of high speed, high load and with reduced weight. It is known in the prior art to use zigzag ...
Static contact pressure distributions are measured and simulated for a slick tire on eight different road surfaces. A fair agreement is obtained between measurements and calculation of contact area, mean pressure and pressure distribution in the contact patch. Thus, the use of this model for tire-...
An instantaneous value connected to length of an indirect contact area of the patch, and another value connected to a hydroplaning phenomenon intensity in the area relative to rest of the patch are deduced from the portion. Water height is estimated from calculation taking into account the former...
