MULTIAXIAL FATIGUE ASSESSMENT OF CHASSIS COMPONENTS ON THE BASIS OF FE MODELS

This article considers finite element modelling for the life assessment of components. It is suggested that local loadings at many surface locations may approximate to uniaxial or proportional multiaxial conditions. A two-stage assessment is therefore proposed as part of the overall durability engineering process. In the first stage critical events and locations are identified through preliminary life estimates and an examination of stress ranges and summary statistics are obtained concerning the behaviour of the elastic stress tensor. A more detailed analysis of the critical events and locations is then carried out with the simplest method appropriate being used. The example of a steering knuckle is described. The stresses at selected nodes are discussed. Athough the component was subjected to complex multiaxial loads, the loadings at the damaged locations were simple.
