    Optimization of Damping Unit

  • Original language description

    This paper reports the numerical investigation and optimization of a damping unit where oil flow interacts with an elastic chocking plate. Chocking of flow from a by-pass valve is the basic principle of hydraulic shock absorbers. However, cavitation phenomenon caused by strong shocking occurs at high frequencies of an actuating movement and the original damping unit characteristic is being distorted. We used the computational fluid dynamic to minimize the distortion of characteristic as much as possible. To satisfy the high number of unsteady simulations, the involved fluid-structure interaction needs to be coupled in a different way than the routine is. The plate deformation is coupled with an average hydrodynamic loading pressure by a single afore-computed third polynomial equation being predicted by FEM. Numerical simulations of flow by the use of FVM exploiting dynamic mesh in Fluent commercial code then provides a flow field pattern and loading pressure within the unit itself. A U
