Abstract:
This communication deals with energy regenerative damping. A two quadrants electro-hydrostatic damper is designed, simulated, manufactured and tested. The proposed damper involves a single rod linear jack, a charging accumulator, a manifold block with four check valves mounted as a full hydraulic rectifier and a hydraulic motor connected to an electrical generator. The proposed top level modelling is performed in order to point out in a simple and efficient way the contribution of both functional and parasitic effects such as inertia, friction, valves cracking pressure and flow rate pressure gradient. On basis these results, the initial design is modified to reduce the motor flow and to admit more conventional components for the demonstrator. A design exploration is run for the components sizing with special consideration to off-the-shelf references. Then, a virtual prototype is built within the LMS-AMESim simulation environment to verify the preliminary design and to assess the damper transient behaviour. Finally, the experimental results measured from the individual test of the first prototype are displayed and analyzed.
