Reliable stress calculation for rotating suspension components by identification of parametric tire models
Abstract
Today the stresses in rotating suspension components under physical load conditions are calculated with a assumed distributions of the contact forces between tire and wheel because the true distributions are not known. This causes uncertainties in the fatigue evaluation and requires an experimental verification of the attained results. The paper describes how the searched force distributions are derived from strains measured on wheels during rolling under load. Target is on the one hand to find out how the wheel loads, the tire presure and tire parameters e. g. the tire height influence the load transfer between tire and wheel and on the other hand to derive distributions of the contact forces for reliable stress calculations. To verify the results identified force distributions are applied to calculate strains which are compared to measured strains.
