AccuFlow developed an innovative technology platform for drug-delivery devices intended for combined use with specialized pharmaceuticals. Within the project, MD-Lab focused on the mechanical pump subsystem: selecting suitable motion mechanisms, designing compact transmission stages, optimizing gear geometry and validating the resulting concepts through simulation and experimental rigs.
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.
MD-Lab research on pumpless Rankine Cycle systems examines compact power generation from low-grade waste heat without the conventional mechanical pump of an organic Rankine cycle. The work combines experimental system development with multi-domain dynamic modelling of heat exchange, valve switching, natural circulation, pressure transients and expander response.
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.
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.
For STASY S.A., MD-Lab developed a repeatable laboratory procedure for assessing the thermal behavior of old rail lubricating grease under controlled heating conditions. MD-Lab designed the thermal-test workflow, configured the heating and temperature-monitoring setup, recorded temperature history and timed observations, and prepared the technical documentation. Supporting chemical analysis was carried out separately by the Fuels and Lubricants Technology Laboratory of NTUA.
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.
