In order to simulate the hysteresis nonlinearity of leaf springs correctly to build an accurate vehicle's dynamic model, a transient dynamic model for leaf springs was established. The hysteresis mechanism of leaf springs was simulated with combined friction elements. The parameters of the model were identified with the adaptive simulated annealing optimization algorithm (ASA) combined with dynamic tests. Finally, employing the proposed model and its identified parameters, a set of simulations under other test conditions were conducted. The good match between other test curves and simulation ones showed that the proposed model can effectively predict dynamic characteristics of leaf springs, so it is an appropriate one for leaf springs.
