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…
Gear Dynamics
MD-Lab research on gear dynamics develops reduced-order, nonlinear and optimization-ready simulation models for spur gear transmissions.

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.
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…
Fluid-Borne Noise Attenuation
MD-Lab research on fluid-borne noise examines compact passive attenuation of pressure pulsations in hydraulic and pipe systems.
