Abstract: A tire damage detection method includes a preliminary stage comprising: performing tests involving test tire impacts against/on different obstacles at different motor vehicle speeds; measuring/acquiring test-related wheel speeds during the performed tests; computing test-related normalized wheel speeds based on the test-related wheel speeds; and determining a predefined tire damage model based on the test-related normalized wheel speeds corresponding to the test tire impacts and of associated test-related average wheel speeds. A tire damage detection stage comprises: acquiring signals indicative of a motor vehicle wheel speed; computing, based on quantities indicative of the wheel speed, a normalized wheel speed indicative of a ratio of the wheel speed to an average wheel speed indicative of motor vehicle speed; and detecting potential damage to a tire of the wheel based on the predefined tire damage model and on the normalized wheel speed.

Abstract: A non-pneumatic tire includes a generally annular inner ring that attaches to a wheel, a generally annular outer ring, and an interconnected web between the generally annular inner ring and the generally annular outer ring. The interconnected web defines a plurality of openings circumferentially spaced around the tire and radially spaced at varying distances from an axis of rotation, so as to support a load by working in tension. The interconnected web includes a plurality of web elements having a varying thickness, including a first plurality of web elements above the axis of rotation and a second plurality of web elements below the axis of rotation. The varying thickness is configured to facilitate buckling of the interconnected web. When a load is applied, the first plurality of web elements are subjected to a tensile force while the second plurality of web elements buckle.

Abstract: A candidate extraction unit (322) executes candidate extraction processing wherein a fixed number of consecutive height data items are extracted from one line of height data using a certain sample point as the starting point, the median for the extracted height data items and the difference therefrom for each extracted height data item are calculated, and sample points with a difference that is at least a height threshold are extracted as singular point candidates. An interpolation unit (323) determines, to be a singular point, a singular point candidate having a number of consecutive repetitions that is less than a width threshold, deletes the height data for the determined singular point, interpolates the deleted height data using height data for sample points which are adjacent to and other than such singular point, and generates shape data for evaluating runout and bulge/dent.

Abstract: A method for producing a finite element model is disclosed. From a contour data set about the original contour shape of an analysis object, a nonuniformly-scaled contour data set about a nonuniformly-scaled contour obtained by anisotropically scaling up or down the contour shape is reconstructed using a scaling factor. The nonuniformly-scaled contour is divided into a finite number of elements and node points are defined to form a primary model. The primary model is anisotropically scaled by the reciprocal of the scaling factor to form the finite element model having the original contour shape.
