Research and Analysis of Stiffness Properties of New Vehicle Air Spring

Abstract:

Based on the analysis of a new type of air spring and the nonlinear finite element theory, this paper, taking the mechanical properties of the new type air spring into consideration, put forward an assessment method: the Mooney-Rivlin model with higher order term simulates rubber layer, the rebar model represents the cord thread layer, the stiffness of the listrium and the controllable damping shock absorber is rigid body, the gas flow and the pneumatophore are in coupling. In addition, the method has been tested and verified by applying to a new type vehicle air spring. This paper offers a new assessment method for the development of air springs in vehicle suspension.
