Analysis of Leaf Spring's Damping Characteristic Based on Nonlinear Finite Element

摘要

In order to know about the damping characteristics of leaf spring in the actual working conditions, the finite element model was build with large deformation, interleaf friction and contact considered simultaneously. In the single sinusoidal excitation, the effects of different friction coefficient, amplitude and excitation frequency on the hysteresis and damping characteristics of leaf spring were studied. Many results were reached in the paper. It provided the references for researching the vibration characteristics of leaf spring further in the nonlinear states.
