NOESIS developed and demonstrated a new generation of vibration and seismic protection devices for all spatial directions. The project was built around the KDamper concept, an innovative isolation and absorption architecture that uses negative-stiffness elements to protect structures, equipment and sensitive installations from seismic and other low-frequency excitations.
The Heart Perfusion project develops a blood-free ex-vivo system for keeping donor hearts viable, assessable and recoverable between organ retrieval and transplantation. Enabled by a patented T3-hormone solution developed by the Department of Pharmacology of the National and Kapodistrian University of Athens and a redesigned perfusion circuit, the work targets longer preservation windows, simpler logistics and substantially lower operating cost.
MD-Lab provided laboratory testing and engineering validation for maritime UAV prototypes developed with A.S. Prote Maritime Ltd. The work covered prototype preparation, static structural checks, dynamic vibration measurements, FFT-based response processing, reverse engineering and aerodynamic simulation support, creating a coherent pathway from physical testing to numerical validation.
A controlled experimental characterization project for ELVAL COLOUR S.A., focused on the damping behavior of composite aluminium plates. MD-Lab developed the mechanical test setup, manufactured a dedicated auxiliary aluminium plate and fixture system, and carried out vibration measurements according to DIN EN ISO 6721-1 and -3. Detailed numerical results and material comparisons are omitted from this public summary due to confidentiality.
The Gearless Differential project investigates a cam-track differential architecture that replaces conventional side and spider gears with identical wavy cam-track disks, guided rolling members and a geared retainer. The work formalizes the geometry required for rolling contact, verifies the kinematics through simulation, and evaluates a representative passenger-car configuration using contact stress and fatigue-life assessment.
MD-Lab research on concrete at cryogenic temperatures develops an experimental route for measuring the linear coefficient of thermal expansion of cylindrical concrete specimens down to approximately -160 °C. The work addresses the need for reliable thermal-strain data in refrigerated liquefied-gas containment structures, where concrete response is governed by coupled heat transfer, pore-water phase change and aggregate-paste mismatch.
Research on plastic gear transmissions at MD-Lab combines material-model development, finite-element and neural-network surrogate modelling, dynamic/NVH simulation, and additive manufacturing technologies. Key results include neural-network surrogates that reproduce finite-element static transmission error curves for polymer gears with 0.49% MAPE, dynamic simulations showing reduced vibration levels compared with metallic gearsets, and additive-manufacturing studies that quantify FDM and other 3D-printing accuracy limits while investigating wear resistance and wear patterns in printed gears.
