Simulation of road loads in truck suspensions generally requires leaf-spring models. This paper presents a simple and accurate leaf-spring model that can be effectively used in analytical road load simulations using ADAMS software. The model topology is based on the familiar SAE “three-link” model. The model parameters are identified from static force-deflection test data. Alternatively, the parameters can be identified from a target design specification or from analytical “tests” on a detailed finite element model. The new leaf spring model has been validated for static and dynamic performance using laboratory test data.
