Design of Resource-Efficient Processes and Process chains for Powertrain Components

The research in the "Design of resource-efficient processes and process chains for powertrain components" field of action is developing methods and models which can be used to design energy-efficient process chains using innovative production procedures. The goal of the work is both to achieve a more effective design for the production of components for the drive trains of motor vehicles and utility vehicles, and to improve the operating properties of the individual components. During manufacturing the number of processes required is thus reduced and the remaining working steps are optimised in terms of energy. Another important objective is the reduction in material use, e.g. by using a form that is as close as possible to the end form during forming processes. The improvement of product properties in order to reduce the energy requirement during the usage phase is likewise a starting point. Here solutions for the reduction of friction are being investigated.


Modelling, Analysis and Design of Energy-Efficient Process Chains
The task is to develop methods and instruments that enable processes and process chains to be described in a general form, as well as for specific process and process chain alternatives to be analysed. In the second step these are to be used to verify technical improvements and thus contribute to the proactive design of energy-efficient process chains.
Energy-Efficient Massive Forming
Comprehensive and intelligent technological design of hot working processes, with the objective of more energy efficient process design through the reduction of forming and processing time and of the energy requirement, achieved through the reduction of the forming force and minimal material use, as a result of the careful design of various procedure-dependent initial and intermediate forms.
Final Shape Cutting and the Manufacture of Optimised Surfaces
The goal is the optimisation of final shape cutting processes, the substitution of procedures with new, innovative production concepts and the configuration of improved functional properties of powertrain components.
Analysis and Optimisation of Joining and Assembly Processes
Both technologically speaking and with regard to energy, the joining of individual components and semi-finished products offers promising possibilities for increasing efficiency. In order to guarantee comparability from an energy perspective, joining and defined component handling are considered. Analytical methods are being developed and innovative joining and handling processes accounted for in terms of energy. The goal, in addition to minimising lead time, is to establish indicators relating to energy.
