Main target of the lecture is to convey the basic design principles, dimensioning rules and structural analysis of conventional and sensor-based machine elements and their applications in the following chapters:

1. Hertzian theory, damage accumulation, probability of failure, statistics and basics of machine learning
2. Concepts of sensory machine elements
3. High-strength screw connections and motion screws
4. Rolling bearings and guides
5. Plain bearings
6. Stationary transmissions with involute toothing – Spur and bevel gears
7. Planetary gears
8. Friction clutches and brakes
9. Mastering sensory uncertainty
10. Condition prognosis

The syllabus exceeds the normal textbook content and includes new research results on each topic available progress reports on sensor integration concepts of the research teams “Sensing Machine Elements” and “eTribosystems”.

Information, lecture notes and supplementary materials are available on the e-learning platform Moodle (Moodle_TU_Darmstadt) of the course “Innovative Machine Elements”.

The lecture enables the students to design machine elements resource-saving and in line with requirements. In addition, the possibilities of condition monitoring for machine elements by using their mechanical and electric properties will be shown. So, the optimal operational time of the components can be approached. Furthermore, the basic requirements for machine elements in e-mobility powertrains will be provided.

The documents and records of past lectures can be found in the Moodle course.
