FLUID-DYNAMIC ANALYSIS IN VEHICLE DESIGN

Mircea DIUDEA, Victor HODOR

Abstract


The design of modern automotive suspension dampers for involve many simulations and tests on test stands and road tests. An accurate analysis of the conditions of flow  within the damper, the required changes to the joint effect from the compressibility of the fluid flow and reaction constructive. This study elements refers to the behavior of fluid flow within the damper, the interstitial area of the piston and the ring floating. Differences are analyzed in this paper fluid flow characteristics within the context of changing damper piston diameter holes in but keep the same surface area of the retirement of the two chambers of the piston in this paper presents a specific approach to a CFD study, conducted with the use of Ansys Fluent in the area of interest was treated as non-stationary with a deformable mesh and that was only possible using LES model.

Key words: vehicle rolling, damper, flow, CFD,  deformable mash, spectral analyze
