Robust FE analysis of radial tires under steady-state traction

摘要

Steady-state tire behavior, expressed by so-called forces and moments, depends strongly on the tire construction: the dependency of lateral and longitudinal force, as well as self-aligning moment on corresponding slip inputs, is controlled by many tire parameters including belt angle and belt width. In order to get a high degree of tire performance as close as possible to the wishes of customers, tire construction has to be optimized, either by tests with prototypes, or by virtual testing - the latter to save time and cost. The first aim of this paper is to describe a new, robust, reliable method for computing the steady-state behavior of radial tires based on contact dynamics and non-linear FE modeling. A second aim is to illustrate the sensitivity of the design parameter belt angle with respect to longitudinal and lateral direction.
