Modeling and Analysis of Inertial-Hydraulic Power take-off Device

open access: yesJournal of Physics: Conference Series
Abstract This paper introduces a novel power output device that combines inertia and hydraulics, which captures vibrations caused by external forces acting on the carrier in space using the sensitive gyroscope of the inertia system. The captured random mechanical energy is then converted into hydraulic energy, rectified and regulated by ...

Wave Energy Converters and Hydraulic Power Take-off: analysis of a possible control strategy

open access: yesJournal of Physics: Conference Series, 2023
Abstract Wave energy conversion is one of the most promising but untapped worldwide technologies. In fact, wave energy is clean and renewable as the solar and wind ones, but also less mature and utilized. Moreover, several Wave Energy Converters (WECs) patents have been developed in the last decades, as evidence of the great potential ...

Energy harvesting from vehicular traffic over speed bumps: A review [PDF]

open access: yes, 2018
Energy used by vehicles to slow down in areas of limited speed is wasted. A traffic energy-harvesting device (TEHD) is capable of harvesting vehicle energy when passing over a speed bump. This paper presents a classification of the different technologies

Multimodal Mechanical Testing of Additively Manufactured Ti6Al4V Lattice Structures: Compression, Bending, and Fatigue

open access: yesAdvanced Engineering Materials, EarlyView.
In this experimental study, the mechanical properties of additively manufactured Ti‐6Al‐4V lattice structures of different geometries are characterized using compression, four point bending and fatigue testing. While TPMS designs show superior fatigue resistance, SplitP and Honeycomb lattice structures combine high stiffness and strength. The resulting

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.
