摘要： A system and method for modeling a distribution of a tire footprint boundary (202) include inputting a finite element model of a tire rolling against a road surface described by discrete road surface coordinates into a finite element analysis system (100). A finite element analysis simulation of tire model rolling against the road surface for a plurality of time increments is performed. A plurality of tire footprint boundary (202) data are generated, each having road surface coordinates on which a footprint boundary (202) overlaps during a unique one of a second plurality of time increments. The number of second plurality of time increments during which the footprint boundary (202) overlaps the each of the discrete road surface coordinates is determined for each of the time increments of the simulation. For each coordinate, the number of the second plurality of time increments may be associated with a color scale or grayscale (510).

摘要： An apparatus and method are disclosed for modeling at least a portion of a rolling tire (200). A finite element model of at least a portion of a tire (200) rolling against a tire contacting surface (202, 506, 602) is input into a finite element analysis system (100). The system executed instructions that result in the application of a constant force to the model tire (200) or portion thereof by the tire contacting surface (202, 506, 602). The application of force control boundary conditions, as opposed to displacement control, provides significant benefit in terms of computational time of the finite element analysis solution. A finite element analysis simulation of the model against the tire contacting surface (202, 506, 602) is performed while maintaining the force on the model tire (200). Alternatively, a camber (γ) is also applied to the tire and maintained throughout the simulation.

摘要： A tire includes a circumferential tread having a tread element disposed thereon, wherein the tread element includes a top surface that defines a first plane. The tire further includes at least one substantially helicoid-shaped sipe disposed in the tread element. The substantially helicoid-shaped sipe is defined by an opening in the top surface extending in a first direction in the first plane when the tire is new, and is further defined by a base extending in a second direction in a second plane parallel to the first plane. The second direction is disposed at an angle between 45° and 135° with respect to the first direction.

摘要： A tire includes first and second sides defining first and second rotation directions. The first rotation direction is in a counterclockwise direction when the tire is viewed from the first side, and the second rotation direction is in a clockwise direction when the tire is viewed from the first side. The tire further includes a carcass ply extending from a first bead portion to a second bead portion, and a circumferential tread disposed above a belt. At least one of the circumferential tread and the carcass ply causes the tire to exhibit a first tire performance when the tire is rotated in the first rotation direction, and a second tire performance that is different from the first tire performance when the tire is rotated in the second rotation direction. The tire performance is selected from the group consisting of braking, dry driving traction, wear performance, and snow traction performance.
