tire with optimal properties to ensure the ride comfort of a vehicle, with the wheels through the parameters of a mathematical ersatzmodels is presented

摘要

A tyre (70) for a vehicle, that is representable by a dynamic rigid-ring tyre model (1) with concentrated parameters, has construction features that are substantially equivalent to concentrated parameters that fall within the following intervals corresponding to preselected indices of comfort: rb = 100 - 300 (Ns/m) rbt = 2 - 40 (Nms/rad) rcz = 100 - 350 (Ns/m) rct = 10 - 90 (Nms/rad) Ckx = 18,000 - 70,000 (N), where rb is a radial foundation dampening of said dynamic tyre model (1); rbt is a torsional foundation dampening of said dynamic tyre model (1); rcz is a residual radial dampening of said dynamic tyre model (1); rct is a residual torsional dampening of said dynamic tyre model (1); and Ckx is a slipping stiffness of a brush model of said tread (71).
