Evaluation of tyre models for durability loads prediction using a suspension-on-a-drum environment

Abstract

The tyre models FTire and LMS CDTire for multibody simulation have been developed for use in the field of vehicle system dynamics. These tyre models are expected to enable us to predict the forces on the wheel spindle in ride comfort and durability simulations. In this paper, the performance of FTire and LMS CDTire in predicting durability loads is evaluated using a new test setup termed a ‘suspension on a drum’. Both tyre models demonstrated a sufficient level of performance to enable practical application in predicting durability performance.
