Project Description
As of right now, there is no method that makes it possible to reliably describe the thermally induced long-term damage behavior of wet multi-plate clutches of different sizes and lining types on the basis of quantifiable parameters. With the aim of closing this research gap, a "damage model for multi-plate clutches" is to be developed within the framework of the research project by means of a synthesis of theoretical and experimental investigations of the thermal behavior and the damage behavior, which enables quantification of the thermally induced damage behavior for various friction systems.
The central focus of the investigation is the identification and analysis of thermal parameters and parameters for the description of the damage behavior as well as their combination in the "damage model multi-plate clutches". Theoretical investigations will focus on thermal behavior, while experimental investigations will concentrate on thermally induced damage behavior and the resulting changes in friction behavior.
By developing the damage model, it will be possible to make well-founded statements regarding the damage behavior and service life of wet multi-plate clutches on the basis of characteristic values. This enhances the understanding and controllability of thermally induced damage mechanisms and achieves application optimization with the aid of derived design guidelines.
The benefit for small and medium-sized companies, which usually have only limited funds to spend on research and development, results from the creation of basic knowledge and simple applicability of the results both in the design of new friction systems (efficiency increase, optimized component dimensioning, reduction of safety tests) and in the investigation of the damage and service life behavior of wet multi-plate clutches.
