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 protection and computationally efficient early-stage optimization.
MD-Lab research on double-flank roll testing converts a fast industrial gear inspection method into a richer diagnostic tool. The work links radial composite error measurements with numerical simulation of free-form meshing gears and inverse models for identifying gear-parameter deviations.
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 as waste heat, solar thermal energy, biomass and combustion outside the working volume.
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 without relying on impractically long side branches.
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 adjustment of lubricant-film stiffness, damping and vibration transmission in rotating machinery.
