Development of a MATLAB toolbox for hydraulic systems with fluid-structure interaction in the frame of hydraulic noise reduction.

摘要

Hydraulics systems have become unavoidable in most cutting edge industries. They indeed permit to reach a consistently high level of precision, to achieve important energy savings and can withstand tremendous loads as for mechanics systems. However, among “hydraulic” flaws, one of them is the main manufacturer’s concern and a source of discomfort for anyone having to sustain it, the hydraulic noise. Some soft wares already provide a simulation tool for hydraulics systems and thus for hydraulic noise but none of them are taking into account the interaction between the fluid and its support structure. For this reason we propose to create a toolbox using SimscapeTM, a simulation interface for MATLAB®, which will contain any component that a hydraulic system can incorporate aiming to have a simple and efficient tool for the simulation of these hydraulics systems, and particularly that of a plane, and to study theudnoise created taking into account the structure-borne noise which plays a fundamental part in the noise generation. The aim is therefore to provide a toolbox as operating and complete as possible for this expressed need.
