Gear Optimization
Multi-objective optimization of gear tooth profiles to improve weight, efficiency, dynamic behavior, and wear performance, focusing on both involute macro-geometry and free-form non-involute profiles. Key results include more than 40% reduction in power losses and 35% reduction in vibration RMS…
Plastic Gears
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…
Magnetic Gears
MD-Lab research on coaxial magnetic gears develops fast analytical and hybrid electromagnetic models for torque prediction, topology evaluation, nonlinear dynamic response and eddy-current loss estimation. The work supports the design of contactless transmissions with reduced wear, low noise, inherent overload…
External Heat Engines Modelling
MD-Lab research on external heat engines develops design-oriented thermodynamic models for Stirling and Ericsson machines. The work focuses on transient heat transfer, real-cycle losses, valve timing and experimentally grounded performance prediction for engines that can use external heat sources such…
Fluid-Borne Noise Attenuation
MD-Lab research on fluid-borne noise examines compact passive attenuation of pressure pulsations in hydraulic and pipe systems. The work extends the classical Herschel-Quincke interference silencer by introducing modulated branch properties, creating a tunable route to additional and broader transmission-loss bands…
3D-Printing Accuracy
MD Lab research on material-extrusion accuracy follows two complementary routes. One determines whether printed holes and shafts will assemble as intended through ISO-GPS coordinate metrology. The other determines printer performance through a compact self-assessment benchmark that turns cylinder form error…
Active Wave Journal Bearing
MD Lab research on active bearings investigates a hydraulically actuated monolithic journal bearing that can change its inner geometry during operation. The concept uses controlled pocket pressure to transform a nominally cylindrical bearing surface into a three-wave profile, enabling real-time…
Upcycling Laboratory Equipment
MD Lab research on design for upcycling investigates how retired mechanical equipment can be converted into high-value, polyfunctional laboratory test rigs. The work combines circular-economy principles with detailed mechanical design, finite element assessment, remanufacturing and modern instrumentation to reduce cost,…
