Institute of Machine Elements, Gears and Tribology

Inst. of Machine Elements, Gears & Transmissions

The Institute of Machine Elements, Gears, and Transmissions (MEGT) at the University of Kaiserslautern was established in 1978 and is headed today by Prof. Dr.-Ing. Bernd Sauer. Over the past few years the team of researchers has been increased to 15, supported by approximately 30 Student assistants. In addition to offering general courses in machine elements, MEGT conducts state-of-the-art research in the field of drive technology, especially chain drives, roller and ball bearings, and radial lip seals. For any of these various machine elements, MEGT has the ability to conduct both component testing and computer-aided dynamic simulations.

The site facilities are equipped with the latest test rigs. Most of these were developed at MEGT for investigating the behavior of specific machine elements. Examples include specialized rigs for measuring the friction moment of roller and ball bearings or the leakage of radial lip seals under dynamic loads. In addition, the test facilities contain a modular, dynamic test rig for drive train components. Equipped with the latest measuring devices, any of these rigs are able to measure and record multiple parameters simultaneously.

Parameters that can’t be measured are obtained through dynamic simulation. The MEGT has created and is continually developing sophisticated finite-element (FE) and multi-body-simulation models (MBS). These are based on commercial simulation software like ANSYS, ADAMS, RecurDyn and SIMPACK. The MBS-models are built up with user written subroutines to provide the necessary, additional functionality. Wherever necessary for proper simulation results, component deformation is also considered. In order to ensure the quality of the simulation, all models are verified with experimental results.
