## Properties

• Semester hours: 2.0
• Credits: 2.0
• Type: UE Exercise

## Learning outcomes

After successful completion of the course, students are able to...

• analyze 2D-mechanisms  and teir properties
• use correctly terms as "applied forces", "constrain forces" and mass forces"
• calculate and minimize the degree of non-uniformity in drive systems
• analyze and understand vibrations of linear multi-degree of freedom systems
• solve complex problems in modelling of torsional vibration systems
• answer basic questions related to bending vibrations of rotating machines
• foresee the effects of mechanical vibrations on humans

## Subject of course

Introductory Problems: Belt drives, impact response of a SDOF-system, etc., flywheel design - Problems on machine foundations: Design parameters of a SDOF-foundation system, etc. - Problems on torsional vibration systems: assembly of system matrices, transformation to reference speed, planetary gearing system, forced torsional vibrations, start up simulation of drive trains, etc. The selection of the problems is subject of changes.

## Teaching methods

Three different lecture formats are used:

• Lecture exercises: The LVA leaders present selected examples. This is done using an overhead projector or via the data projector, rarely on the blackboard. There will be enough time for Q&A and discussions about the solution and the results.
• Group exercises (compulsory attendance): The students try to solve examples in small groups. LVA leaders and tutors help and support. The results are not collected and therefore not rated!

• Colloquia (compulsory attendance): In two written tests (middle and end semester), examples have to be solved, open book tests, but no teamwork.

## Examination modalities

The performance assessment is based on three criteria:

• Results of the colloquia
• Subjective assessment of participation in group exercises by LVA leaders and tutors
• Attendance check at group exercises and colloquia

## Previous knowledge

Der schwingungstechnische Inhalt der Vorlesung Mess- und Schwingungstechnik wird vorausgesetzt!

Erwünscht ist auch eine absolvierte Vorlesung Mechanik 2, weil die Vorlesung und Übung Maschinendynamik teilweise auf den Inhalten der Mechanik 2 Vorlesung und Übung aufbaut.
