Abstract To simulate the nonlinear hysteresis of leaf springs accurately and enable the model of vehicle dynamics to make precise predictions, a transient model is established. The hysteresis of leaf springs is simulated by a combination of friction elements, and the parameters of the model are identified from a set of test data via an optimization that called adaptive simulated annealing algorithm (ASA). Finally, by employing the proposed model and the identified parameters, a set of simulations under other test conditions are carried out. The perfect match between the test curves and the simulations shows that the proposed transient model of leaf springs can effectively predict the dynamic characteristics of the leaf springs.

Key words： leaf springs transient model parameter identification hysteresis
