History

The Laboratory of Machine Elements and Machine Design (LMEMD) belongs to the Design and Structures Department of the School of Mechanical Engineering of the Aristotle University of Thessaloniki, Greece.

It was founded in 1973 as Chair of Machine Elements. In 2002 it was assigned its current legal status and it was included in the Design and Structures Department.

The educational activities of the Laboratory of Machine Elements & Machine Design include many courses to the students of the Aristotle University of Thessaloniki. Courses include tribology, machine elements, strength of materials and others.

The research activities cover the fields of engineering design, EHL, tribology, strength analysis and fatigue testing of machine elements as well as complete machines

The Laboratory of Machine Elements & Machine Design was headed by Prof. Dr. Ing. Robert Grekoussis until his recces in 1992. Prof. Dr. Ing. Georgios Athanassiadis took over and directed the Laboratory until he died in 2007. From 2007 until 2019 the Laboratory was directed by Prof. Athanasios Mihailidis.

To the postgraduate students of the Intersectional Programme on Protection, Conservation and Restoration of Cultural Monument, Aristotle University of Thessaloniki it offers the course

• Laboratory training for Infrared Reflectography

The research activities of the Laboratory of Machine Elements and Machine Design (LMEMD) are focused on the following fields:

• Design and Tribology of Machine Elements and Power Transmission Systems
• Strength and Fatigue of Machine of Elements and Parts
• Computer Aided Engineering
• Mechatronics and non-destructive testing
• Automotive Engineering

Experiments are carried out on an FZG-type back-to-back test rig featuring the patented VarioTorque system, on a two disk test machine and on two pulsers with maximum load 400 kN and 10 kN respectively as well as on a rotating bending test machine.

The Laboratory of Machine Elements and Machine Design (LMEMD) provides technical support in the following areas:

• Measurement of scuffing capacity of gear lubricants on a FZG-test rig of axial distance 92.5 mm according to DIN 51354.
• Friction coefficient measurements in a crossed-axes disk rig with axial distance 100mm.
• Fatigue tests on a pulser ± 500 kN (Schenck Hydropuls 50).
• Design and load carrying capacity calculation for spur and helical gear pairs according to DIN 3990.
•  Design of machine elements and power transmission systems.
• Complete design and analysis of frames and car bodies.
• Stress and deformation analysis of general structures using the Finite Element Method (FEM).
• Software development of CAD (Computer Aided Design), CAE (Computer Aided Engineering) and CAD/CAE integration systems.
• Virtual Reality and Animation software development for the simulation of real objects and actions.
•  Development of special algorithms for FEM, BEM and Computer Graphics.

The services provided by LMEMD are charged according to the employment of the scientific and technical staff and the cost of the necessary consumable materials. During the design of the services mentioned the current national and international regulations and the corresponding legislation apply.
