A Computational Fluid Dynamics (CFD) method, combined with a dynamic modeling technique were introduced to study the flow and performance of automotive hydraulic damper/shock absorbers. The flow characteristics of component obtained byusing CFD was applied todynamic modeling package to predict the damping force. The component CFD analysis showed unique features as far as flow part tern, discharge coefficients and pressure distribution for various shock absorber components. Dynamic damper model was constructed by using a commerical package Easy5 with flow information provided by CFD. A simple representation of the complicated design of shocks as a network of fixed and variable restrictions in series and parallel connected by compliant volumes of oil is suitable for capturing the dynamics important to vehicle handling simulations.
