The Research Center for Gears and Gear (short form: FZG ), the Institute for Machine Elements of the Technical University of Munich (TUM), is a research institute for drive technology in the field of engineering discipline engineering . Karsten Stahl is the leading professor .

history

The research center was founded in 1951 by Gustav Niemann , who began with pioneering work in the research areas of gears and gear construction . These areas of research were essentially retained under Hans Winter , who followed Niemann in October 1968. In October 1989, Bernd-Robert Höhn succeeded Winter as full professor at the Chair of Machine Elements at TUM . Under his leadership the previous research activities were around the areas infinitely variable transmission and autonomous hybrid drive for motor vehicles expanded. Karsten Stahl has headed the chair since 2011 .

The FZG forms the competence center for questions of mechanical drive technology at the Faculty of Mechanical Engineering at TUM . In research and development as well as in standardization , the FZG plays a central role nationally and internationally in the field of drive and transmission technology.

The research projects of the FZG range from theoretically oriented basic work to application-oriented experimental work. The projects are financed and supported by different organizations. The majority of the projects are initiated, financed and supervised by the Research Association for Drive Technology (FVA), mostly together with the Working Group of Industrial Research Associations (AiF). Other research partners are the German Research Foundation (DFG), the Bavarian Research Foundation , the German Scientific Society for Petroleum, Natural Gas and Coal (DGMK), the Research Association for Combustion Engines (FVV) and steel research. In addition, application-oriented projects are requested and commissioned directly by the industry.

Every 2 years, the VDI International Conference on Gears, the VDI International Conference on Gear Production and the VDI International Conference on High Performance Plastic Gears are held at the FZG .

research

Experimental and theoretical investigations on transmission components and drive systems form the core of the research content at the FZG.

Overview of the research content and activities at the FZG

Components

An essential part of the research activities at the FZG examines the components of transmissions. These include in particular

Drive systems / electromechanical drives

In addition to the components, there is also a focus on the conception, simulation and experimental investigation of various drive systems and their implementation in real vehicle prototypes and various applications.

Focus

The components and drive systems / electromechanical drives are examined at the FZG with a focus on the following criteria:

Simulation and calculation programs

Various application programs in the field of component and drive development were developed at the FZG. A selection is shown below:

program use
Cap First design of gearboxes
Edge generator Generation of any tooth geometry
STplus Calculation of tooth geometry and load capacity of spur gears according to DIN 3990, ISO 6336, AGMA and other calculation methods
KNplus Calculation of bevel gear geometry and bevel gear load capacity according to ISO 10300 and other methods
STOCK2 Calculation of the roller bearing stiffness (internal loads and pressures) and the (modified reference) bearing life according to DIN ISO 281
RIKOR Calculation of shaft deformation, bearing sag, tooth flank corrections, load distribution in tooth contact, damage-relevant loads and contact pattern for straight, helical and double helical gears
WTplus Determination of the efficiency and heat balance of any manual, automatic and industrial gearboxes
DZP Calculation of rotary path errors, force excitation, natural frequencies and additional dynamic forces in straight and helical gear units
RIKOR2DYN Dynamic transmission analysis
ANPLA Determination of the excitations for planetary gear sets
SNESYS Design and recalculation of worm gears
SYNTEM Calculation of the temperature development in a gearbox synchronization during a shift (internal, external, double or triple cone synchronizers with largely free choice of friction surface structure / geometry)
KUPSIM Calculation of the temperature balance in multi-plate clutches / brakes taking into account the heat dissipation through the oil for individual friction phases and cooling phase collectives

In addition, computational studies are carried out through simulation using the Finite Element Method (FEM) and Computational Fluid Dynamics (CFD).

As part of the FVA third-party funded research, the "Software Manager" position was set up at the FZG to provide comprehensive support for transmission software. This serves to preserve, secure the future and modularize existing software as well as to ensure a sustainable software development strategy across all programs. For existing software, the FZG also serves the FVA member companies as a contact in the field of computer application in drive technology. In addition, there is close cooperation with FVA GmbH to further develop the FVA Workbench . Many of the listed FZG calculation programs are included. Some of the programs for transmission calculation that are widely used and recognized in German drive technology were and are being developed at the FZG.

Projects and dissertations

Various projects and research projects since 1951 have resulted in 227 dissertations from the FZG (as of January 31, 2019).
