Current research projects
In cooperation between an OEM and the chair for vehicle system design, two Ph.D. students will be working on the topic of digital tire development from 2019 with the aim of specifying a virtual vehicle prototype with regard to tire properties in the widest possible speed range.

Univ.-Prof. Dr.-Ing. Ralph MayerBased on a thermal analysis of the wheel brake, requirements for the brake are examined taking into account new conceptual framework conditions. With the aim of prototypical implementation, the project will be operated with two other research institutions (project start: 2018).

The aim of the new development concept is the combination of functional and design-optimized product design with multiple functional integration without restrictions caused by todays platform and modul strategies or manifested supply chains. In cooperation with 6 other professures of TU Chemnitz this project was started in 2018.

The NVH behavior of a vehicle ranges from low-frequency (vibration) to high-frequency and thus in an acoustically effective range. Cause can be the powertrain (torsional and bending vibrations, vibration transfer, noise radiation) but also affect the suspension. In the environment of increasing lightweight construction measures in the vehicle (for example, material mix in the body) and electrification of the powertrain however, additional frequency spectra in the area of cause, transmission and effect must be taken into account.
In the project, the natural frequency and damping behavior of different brake discs (solid and ventilated brake disc, composite brake discs) is determined by various influencing factors, such as: Corrosion, use beyond the wear limit, etc. factor-individually examined us statistically evaluated. The first presentation of the results was held during the conference chassis.tech in June 2018.

The focus in this research field is on the analysis, characterization and development of vehicle body vibration dampers (including active systems) with the aim of optimizing properties with regard to responsiveness (dampfer friction) and environmental compatibility. In cooperation with materials scientists, results of basic research in the field of lightweight material construction should be taken into account and enable significant weight reduction on chassis components.

Completed research projects
Das Projekt zielt auf die Methodenentwicklung ab, bereits im frühen Stadium des Produktentstehungsprozesses hochwertige Fahrwerke effizient zu konzeptionieren und zu entwickeln. Neben den funktionalen und geometrischen Anforderungen stehen die Aspekte der gesamten Produktionskette (intern und extern seitens OEM) im Vordergrund.
Erste Ergebnisse sind im Rahmen der Konferenz chassis.tech 2017 veröffentlicht sowie weitere Informationen sind in der Ausgabe 1/2019 der Automobiltechnischen Zeitschrift ATZ zu finden (Doktorand: Bastian Leistner).
