Abstract: A leaf spring is the main component of the mechanical suspension on heavy trucks. The dynamic behavior of the leaf spring is very complex. This research aims to develop a numerical model that reflect the dynamic behavior of different types of leaf springs, such as: double-eye, eye-roller and roller-roller. Tests are performed to experimentally characterize the leaf springs. Then, a hybrid model is developped to represent the dynamic behavior efficiently and at low cost by combining the non-physical model of Bouc-Wen and the Adams Car finite element model. The Bouc-Wen model is non-physical and models the hysteresis behavior of the leaf spring while the finite element model is physical and represents the vertical and longitudinal movements of the leaf spring following the application of a load.
