MD-Lab research on 3D-printed gears studies how additive manufacturing changes both gear design and gear metrology. The work combines free-form tooth-flank optimization for improved wear resistance with CMM-based dimensional accuracy assessment of polymer spur gears produced by FDM, material extrusion and powder bed fusion.
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 geometric dimensioning and tolerancing connects ISO GPS specification, functional performance, datum-system design, finite-element assembly behaviour and inspection strategy for compliant parts and additive-manufactured components.
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 into an accessible displacement measurement.
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.
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, material demand and development time without compromising experimental capability.
The second year students are informed that the make-up of the course Elements of Machinery II, which was lost due…
