Abstract:

Since that the existing SAE three-link leaf spring model represent hysteretic characteristic insufficiently, this paper, based on analyzing the mechanism of hysteretic characteristic, introduces the force element representing the dry friction between leafs into the SAE three-link model by using optimization method. The Comparison of the test and simulation results indicates that the SAE three-link model which imported the dry friction could simulate the hysteretic characteristic of leaf springs well.

Key words: vehicle engineering, vehicle dynamics, leaf springs, hysteretic characteristic
